TCS Interview experience 2013-2014 shared by Samaria on Sept 2013 in Banglore

My TCS interview took place in the last week of Sept 2013.Since I was exempted from written test ,I have only interview part to share.

1 Introduce yourself?

2 tell me about you 2 strength and 2 weaknesses?

3 Which language you are comfortable in?
Ans –those of who answer java ,should keep in mind that java is the language  used mostly for app development, and covers oops and its good lib of functions and modules. so be prepared to answer those.
To be on the safer side I said C++.

4 How do you implement polymorphism in c++?
a) function overloading-answer
b) operator overloading (explain both the methods and why do we need them)

5. Can we perform operator overloading in java?
Ans- yes we can ,although it doesn’t support operator key word. there is some other method for that.

4.why java?
Its portable ,has oops features and good collection of api,gui,and lib functions.

5.How can we do database connections c++?
Ans  Well I haven't done any ,if needed I have always used java.

6.Can we have 2 mains?
Ans I haven’t seen any till date, so No.

7.How is java code portable and how is it exec on JVM.
Ans I had to actually convince the interviewer for this one. Java produces byte code that is zeroes and ones ,which can be executed by any JVM, but JVM IS not platform dependent (he was like ah.. what are u saying …and he went on explaining jdk)I told him that JVM is different for diff OS .Perhaps after this answer he was convinced that I had a bit knowledge about the subject.

8.What is a doubly linked list?

9 Around 3-4 SQL queries asked on JOINS ,select operation (very simple)?

10 Question related to project?
He had no idea about Mobile Ad-hoc networks ,so he was a mute listener.

11.Expain features of OOPS?
Oops=object based+polymorphism+inheritance
Features-encapsulation,Classes and objects,polymorphism,inheritance,message passing.

TCS 2013-2014 Selection Procedure, written test pattern Tech and HR Interview process

Hi friends,
some students shared TCS this years information's from their campuses. 

we are sharing this details for your upcoming TCS Recruitment -preparation. 
These points, sharing as an indicative purposes. Its gives an overview for TCs exam


1. Eligibility criteria
2. Analytical ability test
3. Verbal ability test
4.Interview
5 Selection

2. Analytical ability test:
Questions : 30
Duration : 80 mins
Negative marking: Yes ( 1 for correct answer and negative marking of 0.33 for wrong answer)

3. Verbal ability test:
This is a simple test for about 10 mins. They will be given you a set of 10 keywords and you should frame a passage( within 100 words)
In this test applicants will be assessed based on the proper usage of the given keywords and grammar.

4. Interview sections:

Pure HR Panel:
Easy to clear for the most part, “It is really crucial that you speak good English or atleast try” “. As far as I have seen most people with good English speaking skills were selected

Asked to give a self introduction about themselves

“Are you ready to go anyway we send you are is there a particular place you like most?”

“Do you have a Girl Friend how long have you been together?”(for boys ofc)

They will ask you about your hobbies, if you say painting for example they will ask what you have done to improve your skills in it.

“What is your fathers job?” or “How many brothers and sisters do you have?”.

For most of the HR interviews there was always a family type question, shouldn’t be a problem.

The biggest challenge you have faced so far in college

Why you choose your department and your favorite subjects (basically questions related to why you choose the department and your interests).

THEN THE STRESS TEST:

Here you can expect questions like “you have a low score in your aptitude why?“,

“your marks are consistently low why ?“,

“You don’t sound confident is that why you are speaking so softly “,

“you are an emotional person is it not , you look very tense“.

Remember these statements may or may not be true about you try reply with a smile and positive comment like “I will try hard next time ” or “I will do correct these mistakes” etc. Just don’t burst into tears like some of the girls in my college did NOT GOOD!!!

“How badly do you want this job?”
And of course the most common questions “what did you eat in the morning? “,maybe a slight variation like “you look tired have you had your lunch”.

Then there was some questions on details about the company like “who is the CEO”, “What do you know about TCS”, “Do you know what sector in IT TCS working”. 

For these make sure you visit the campus commune website and read all the details.

“What are you expecting from TCS?”. For this just prepare a well rehearsed answer like “To improve my skill and abilities in such a way that it is mutually beneficial to company and me” (What 2 of my friends said , both selected of course)

Some questions from the resume, your co-curricular achievements , extra-curricular achievements. In some cases the programming languages you know about.

Then some of the HR’s asked questions logical questions like 

“Two people start from Delhi and Pune one traveling at 20km/hr and the other 160km/hr in opposite directions both meet at a point who is closer to Pune?”

The answer is easy both as same distance since it is mentioned that they meet, THE KEY HERE IS TO LISTEN CAREFULLY TO WHAT THEY ARE SAYING, some of my friends from other colleges did not answer and thought the one going at 160km/hr was closer.

Be prepared for questions of this type testing your concentration.

“Are you going to do higher studies some time?”

“what is the hardest data structure for you “My friend said Trees, the HR are was like “Trees really what about graphs, the LOLed real loud”

“about the various certification programs you have completed and why you took them”

Tech Panel:
To be honest this isn’t hard really, all questions are simple nothing deep and tough.

Some of the Interviewers did not even look at the code my friends wrote they just took the paper and used it as paper fans :) ,

Programming, Data Structures and project related

“Write a java code using try catch statements“


“Explain about your project, implementations, front-end, back-end, technical details etc” BE extra through about the details of all your projects

“code to implement a link list in C”. “write it using pointers”

Some will ask you to write code from your projects (For some mechanical students theory behind functionality of the project)

swap function without using temp variable

Explain linked list concept /stack/queue/trees

Explain different types of sorting

What is a null pointer, void point and a wild pointer

Explain the object oriented concepts in java (polymorphism, inheritance,encapsulation )

Then the sizes for various data types in C and Java

Program using thread/overriding/overloading in java.

Infix/postfix/prefix convertions

Java database connectivity.

what is a constructor?

other programs like prime numbers, odd/even easy stuff basic programming

Networks and OS

OSI layers in network model and functions of each layer

Difference between TCP and UDP

“There are 2 systems in 2 different networks will you use a switch or a router to connect them”

What is the difference between switch, router , bridge

In OS questions related to the fork() command

Scheduling algorithms in OS

What is a semaphore

How many bits in an IP address

Draw a rough sketch of an IP packet

Layers of TCP/IP

A few questions related to the linux file system

Questions related to network address and host address

How is windows 7 different from XP

what is paging and questions related to that.

process life cycle

What is the ping command used for?

Database and Testing

This was all really easy MySQL queries which included select statements using where condition etc, very easy queries.

Also some questions about normal forms, 1NF ,2NF, CNF.

Black box and white Box testing differences

Types of testing?

What is a test case?

Software life cycle models(waterfall models etc)

what is meta data?

Why is testing important?

This section had the most easiest of all questions, just study all the basics.

Other Department Students Tech Panel

Yes there is programming but it is not that deep here are a few samples

“Explain about your project “(most frequent question asked to 80% students i got this information from)
Then the interviewer asks what programming languages you know (most replied C), then he asks you to write a simple programming like prime numbers ,swap without temp etc. In some cases write any C program

To some EEE students the interviewer has ask how the ceiling fan/generator etc works

For  Mech students and 1 ECE student told me that the HR asked them their favorite subject and to explain about it

“what is CAD(he had CAD in his resume)”


Some questions related to data structures basics “what is stack”

Overall Programming and OS concepts are not going to be asked much unless you say you know them.
For example if you say you know java obviously he is going to ask a lot from it. 


Mostly others departments had HR questions only or HR/tech. Everyone I asked said it was nothing tough .Make sure you know C programming , at least the basics.
Tech/HR panel


This is a mix and smash of both types of questions . Basically one HR will ask a tech questions and the second HR will ask a HR questions. My friends kept on talking for all the HR questions he says it help reduced the number of tech questions asked to him (I do not know the degree of effectiveness of this idea :) ). By far these type of panels are easy to clear too.

After a few interviews it should be clear which panel is of which type. In my college the placement representatives were responsible of putting you in a panel, just talk to them depending on which panel you feel comfortable with.

Some important things:

Speak clearly, most of the students who were selected could speak good English

Try not to sweat a lot.

Keep a separate copy of your resume in a stick file.

There was an incident in our college relating to under-performance. Basically some of the students who were already placed went in and said they were placed in such and such company and they don’t want to come to TCS etc or that they don’t like going for a job and want to do higher studies. DO NOT DO THIS IT PASSED OFF THE INTERVIEWERS AND RESULTED IN LESS PLACEMENT COUNT AND IS REALLY RUDE. The head of HR mentioned it during the closing ceremony. IF you want to under perform then do it without it being too obvious. This incident happened in 3 colleges so far as I know, remember do not let your actions effect other :) .(tell your friends who are planning on under performing this)

try wear a tie for boys and girls no high heels(one of the girls in my college tripped and fell in those ).

Selection:

Once you get selected, your offer letter will be provided based on your performance in the online assignments which they give.

TCS APTITUDE PAPER WITH SOLUTIONS
1) If log 0.317=0.3332 and log 0.318=0.3364 then find log 0.319 ?
Sol) log 0.317=0.3332 and log 0.318=0.3364, then
log 0.319=log0.318+(log0.318-log0.317) = 0.3396

2) A box of 150 packets consists of 1kg packets and 2kg packets. Total weight of box is 264kg. How many 2kg packets are there ?
Sol) x= 2 kg Packs
y= 1 kg packs
x + y = 150     .......... Eqn 1
2x + y = 264   .......... Eqn 2 
Solve the Simultaneous equation; x = 114
so, y = 36
ANS :  Number of 2 kg Packs = 114.

3) My flight takes of at 2am from a place at 18N 10E and landed 10 Hrs later at a place with coordinates 36N70W. What is the local time when my plane landed?
6:00 am b) 6:40am c) 7:40 d) 7:00 e) 8:00 
Sol) The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360).
When the flight landed, the time at the starting place is 12 noon (2 AM + 10 hours).
Hence, the time at the destination place is 12 noon - 5:20 hours = 6: 40 AM

4) A plane moves from 9°N40°E to 9°N40°W. If the plane starts at 10 am and takes 8 hours to reach the destination, find the local arrival time ?
Sol) Since it is moving from east to west longitide we need to add both
ie,40+40=80
multiply the ans by 4
=>80*4=320min
convert this min to hours ie, 5hrs 33min
It takes 8hrs totally . So 8-5hr 30 min=2hr 30min
So the ans is 10am+2hr 30 min
=>ans is 12:30 it will reach

5) The size of the bucket is N kb. The bucket fills at the rate of 0.1 kb per millisecond. A programmer sends a program to receiver. There it waits for 10 milliseconds. And response will be back to programmer in 20 milliseconds. How much time the program takes to get a response back to the programmer, after it is sent? Please tell me the answer with explanation. Very urgent.
Sol) see it doesn't matter that wat the time is being taken to fill the bucket.after reaching program it waits there for 10ms and back to the programmer in 20 ms.then total time to get the response is 20ms +10 ms=30ms...it's so simple....

6) A file is transferred from one location to another in 'buckets'. The size of the bucket is 10 kilobytes. Each bucket gets filled at the rate of 0.0001 kilobytes per millisecond. The transmission time from sender to receiver is 10 milliseconds per bucket. After the receipt of the bucket the receiver sends an acknowledgement that reaches sender in 100 milliseconds. Assuming no error during transmission, write a formula to calculate the time taken in seconds to successfully complete the transfer of a file of size N kilobytes.
(n/1000)*(n/10)*10+(n/100)....as i hv calculated...~~!not 100% sure

7) A fisherman's day is rated as good if he catches 9 fishes, fair if 7 fishes and bad if 5 fishes. He catches 53 fishes in a week n had all good, fair n bad days in the week. So how many good, fair n bad days did the fisher man had in the week
Ans:4 good, 1 fair n 2 bad days
Sol) Go to river catch fish
4*9=36
7*1=7
2*5=10
36+7+10=53...
take what is given 53
good days means --- 9 fishes so 53/9=4(remainder=17)  if u assume 5 then there is no chance for bad days.
fair days means ----- 7 fishes so remaining 17 --- 17/7=1(remainder=10) if u assume 2 then there is no chance for bad days.
bad days means -------5 fishes so remaining 10---10/5=2days.
  Ans: 4 good, 1 fair, 2bad. ==== total 7 days.

x+y+z=7--------- eq1
9*x+7*y+5*z=53 -------eq2
multiply eq 1 by 9,
9*x+9*y+9*z=35 -------------eq3
from eq2 and eq3
2*y+4*z=10-----eq4
since all x,y and z are integer i sud put a integer value of y such that z sud be integer in eq 4 .....and ther will be two value y=1 or 3 then z = 2 or 1 from eq 4

for first  y=1,z=2 then from eq1 x= 4
so 9*4+1*7+2*5=53.... satisfied
now for second y=3 z=1 then from eq1 x=3
so 9*3+3*7+1*5=53 ......satisfied
so finally there are two solution of this question
(x,y,z)=(4,1,2) and (3,3,1)...

8) Y catches 5 times more fishes than X. If total number of fishes caught by X and Y is 42, then number of fishes caught by X?
Sol) Let no. of fish x catches=p
no. caught by y =r
r=5p.
r+p=42
then p=7,r=35

9) Three companies are working independently and receiving the savings 20%, 30%, 40%. If the companies work combinely, what will be their net savings?
suppose total income is 100 
so amount x is getting is 80
y is 70
z =60
total=210

but total money is 300
300-210=90
so they are getting 90 rs less
90 is 30% of 300 so they r getting 30% discount

10) The ratio of incomes of C and D is 3:4.the ratio of their expenditures is 4:5. Find the ratio of their savings if the savings of C is one fourths of his income?
Sol) incomes:3:4
expenditures:4:5
3x-4y=1/4(3x)
12x-16y=3x
9x=16y
y=9x/16
(3x-4(9x/16))/((4x-5(9x/16)))
ans:12/19

11) If G(0) = -1 G(1)= 1 and G(N)=G(N-1) - G(N-2) then what is the value of G(6)?
ans: -1
bcoz g(2)=g(1)-g(0)=1+1=2
g(3)=1
g(4)=-1
g(5)=-2
g(6)=-1

12) If A can copy 50 pages in 10 hours and A and B together can copy 70 pages in 10 hours, how much time does B takes to copy 26 pages?
Sol) A can copy 50 pages in 10 hrs.
A can copy 5 pages in 1hr.(50/10)
now A & B can copy 70 pages in 10hrs.
thus, B can copy 90 pages in 10 hrs.[eqn. is (50+x)/2=70, where x--> no. of pages B can copy in 10 hrs.]
so, B can copy 9 pages in 1hr.
therefore, to copy 26 pages B will need almost 3hrs.
since in 3hrs B can copy 27 pages.

13) what's the answer for that :
A, B and C are 8 bit no's. They are as follows:
A -> 1 1 0 0 0 1 0 1
B -> 0 0 1 1 0 0 1 1
C -> 0 0 1 1 1 0 1 0 ( - =minus, u=union)
Find ((A - C) u B) =?

To find A-C, We will find 2's compliment of C and them add it with A,
That will give us (A-C)
2's compliment of C=1's compliment of C+1
=11000101+1=11000110
A-C=11000101+11000110
=10001001
Now (A-C) U B is .OR. logic operation on (A-C) and B
10001001 .OR . 00110011
The answer is = 10111011,
Whose decimal equivalent is 187.

14) One circular array is given(means memory allocation tales place in circular fashion) diamension(9X7) and sarting add. is 3000, What is the address of (2,3)........
Sol) it's a 9x7 int array so it reqiure a 126 bytes for storing.b'ze integer value need 2 byes of memory allocation. and starting add is 3000
so starting add of 2x3 will be 3012.

15) In a two-dimensional array, X (9, 7), with each element occupying 4 bytes of memory, with the address of the first element X (1, 1) is 3000, find the address of X (8, 5).
Sol) initial x (1,1) = 3000 u hav to find from x(8,1)so u have x(1,1),x(1,2) ... x(7,7) = so u have totally 7 * 7 = 49 elementsu need to find for x(8,5) ? here we have 5 elements each element have 4 bytes : (49 + 5 -1) * 4 = 212 -----( -1 is to deduct the 1 element ) 3000 + 212 = 3212

16) Which of the following is power of 3 a) 2345 b) 9875 c) 6504 d) 9833

17) The size of a program is N. And the memory occupied by the program is given by M = square root of 100N. If the size of the program is increased by 1% then how much memory now occupied ?
Sol) M=sqrt(100N)
N is increased by 1%
therefore new value of N=N + (N/100)
               =101N/100
M=sqrt(100 * (101N/100) )
Hence, we get M=sqrt(101 *  N)

18)
1)SCOOTER --------- AUTOMOBILE--- A. PART OF
2.OXYGEN----------- WATER ------- B. A Type of
3.SHOP STAFF------- FITTERS------ C. NOT A TYPE OF
4. BUG -------------REPTILE------ D. A SUPERSET OF
1)B    2)A       3)D     4)C

19) A bus started from bustand at 8.00a m and after 30 min staying at destination, it returned back to the bustand. the destination is 27 miles from the bustand. the speed of the bus 50 percent fast speed. at what time it returns to the bustand
this is the step by step solution:
a bus cover 27 mile with 18 mph in =27/18= 1 hour 30 min. and it wait at stand =30 min.
after this speed of return increase by 50% so 50%of 18 mph=9mph
Total speed of returnig=18+9=27
Then in return it take 27/27=1 hour
then total time in joureny=1+1:30+00:30 =3 hour
so it will  come at 8+3 hour=11 a.m.
So Ans==11 a.m

20) In two dimensional array X(7,9) each element occupies 2 bytes of memory.If the address of first element X(1,1)is 1258 then what will be the address of the element X(5,8) ?
Sol) Here, the address of first element x[1][1] is 1258 and also 2 byte of memory is given. now, we have to solve the address of element x[5][8], therefore, 1258+ 5*8*2 = 1258+80 = 1338 so the answer is 1338.

21) The temperature at Mumbai is given by the function: -t2/6+4t+12 where t is the elapsed time since midnight. What is the percentage rise (or fall) in temperature between 5.00PM and 8.00PM?

22) Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day.  Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?
Sol) Let highest temp be x
so low temp=1/3 of x of 1/2 of x plus x/2 i.e. x/6+x/2
total temp=x+x/6+x/2=100
therefore, x=60
Lowest temp is 40

23) In Madras, temperature at noon varies according to -t^2/2 + 8t + 3, where t is elapsed time. Find how much temperature more or less in 4pm to 9pm. Ans. At 9pm 7.5 more
Sol) In equestion  first put t=9,
we will get 34.5...........................(1)
now put t=4,
we will get 27..............................(2)
so ans=34.5-27
         =7.5

24) A person had to multiply two numbers. Instead of multiplying by 35, he multiplied by 53 and the product went up by 540. What was the raised product?
a) 780     b) 1040   c) 1590   d) 1720
Sol) x*53-x*35=540=> x=30 therefore, 53*30=1590 Ans

25) How many positive integer solutions does the equation 2x+3y = 100 have?
a) 50   b) 33   c) 16    d) 35
Sol) There is a simple way to answer this kind of Q's given 2x+3y=100, take l.c.m of 'x' coeff and 'y' coeff i.e. l.c.m of 2,3 ==6then divide 100 with 6 , which turns out 16 hence answer is 16short cut formula--- constant / (l.cm of x coeff and y coeff)

26) The total expense of a boarding house are partly fixed and partly variable with the number of boarders. The charge is Rs.70 per head when there are 25 boarders and Rs.60 when there are 50 boarders. Find the charge per head when there are 100 boarders.
a) 65    b) 55   c) 50   d) 45
Sol) 
Let a = fixed cost and k = variable cost and n = number of boarders
total cost when 25 boarders c = 25*70 = 1750 i.e. 1750 = a + 25k
total cost when 50 boarders c = 50*60 = 3000 i.e. 3000 = a + 50k
solving above 2 eqns, 3000-1750 = 25k i.e. 1250 = 25k i.e. k = 50
therefore, substituting this value of k in either of above 2 eqns we get
a = 500 (a = 3000-50*50 = 500 or a = 1750 - 25*50 = 500)
so total cost when 100 boarders = c = a + 100k = 500 + 100*50 = 5500
so cost per head = 5500/100 = 55

27) Amal bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8 erasers and 14 pencils for an amount which was half more than what Amal had paid. What % of the total amount paid by Amal was paid for pens?
a) 37.5%     b) 62.5%   c) 50%   d) None of these
Sol) 
Let, 5 pens + 7 pencils + 4  erasers = x  rupees
so 10 pens  + 14 pencils + 8 erasers = 2*x rupees
also mentioned, 6 pens + 14 pencils + 8 erarsers = 1.5*x rupees
so (10-6) = 4 pens = (2-1.5)x rupees
so 4 pens = 0.5x rupees => 8 pens = x rupees
so 5 pens = 5x/8 rupees  = 5/8 of total (note x rupees is total amt paid byamal) 
i.e 5/8 = 500/8% = 62.5% is the answer

28) I lost Rs.68 in two races. My second race loss is Rs.6 more than the first race. My friend lost Rs.4 more than me in the second race. What is the amount lost by my friend in the second race?
Sol)
x + x+6 = rs 68
2x + 6 = 68
2x = 68-6
2x = 62
x=31
x is the amt lost in I race
x+ 6 = 31+6=37 is lost in second race
then my friend lost 37 + 4 = 41 Rs

53) There is a six digit code. Its first two digits, multiplied by 3 gives all ones. And the next two digits multiplied by 6 give all twos. Remaining two digits multiplied by 9 gives all threes. Then what is the code?
sol) Assume the digit xx xx xx (six digits)
First Two digit       xx * 3=111
                     xx=111/3=37
( first two digits of 1 is not divisible by 3   so we can use 111)
Second Two digit xx*6=222
                xx=222/6=37
( first two digits of 2 is not divisible by 6   so we can use 222)
Thrid Two digit    xx*9=333
                  xx=333/9=37
( first two digits of 3 is not divisible by 9   so we can use 333)

54) There are 4 balls and 4 boxes of colours yellow, pink, red and green. Red ball is in a box whose colour is same as that of the ball in a yellow box. Red box has green ball. In which box you find the yellow ball?
ans is green...
Sol) Yellow box can have either of pink/yellow balls.
if we put a yellow ball in "yellow" box then it wud imply that "yellow" is also the colour of the box which has the red ball(becoz acordin 2 d question,d box of the red ball n the ball in the yellow box have same colour)
thus this possibility is ruled out...
therefore the ball in yellow box must be pink,hence the colour of box containin red ball is also pink....
=>the box colour left out is "green",,,which is alloted to the only box left,,,the one which has yellow ball..

55) A bag contains 20 yellow balls, 10 green balls, 5 white balls, 8 black balls, and 1 red ball. How many minimum balls one should pick out so that to make sure the he gets at least 2 balls of same color.
Ans:he should pick 6 ball totally.
Sol) Suppose he picks 5 balls of all different colours then  when he picks up the sixth one, it must match  any on of the previously drawn ball colour.
thus he must pick 6 balls

56) What is the number of zeros at the end of the product of the numbers from 1 to 100
Sol) For every 5 in unit palce one zero is added 
so between 1 to 100 there are 10 nos like 5,15,25,..,95 which has 5 in unit place.
Similarly for every no divisible by 10 one zero is added in the answer so between 1 to 100  11 zeros are added
for 25,50,75 3 extra zeros are added
so total no of zeros are 10+11+3=24

No two watches show the same time. The difference between the watches is 2,3,4,5 respectively. Whose watch shows maximum time?
sol) A shows 11:57, B shows 12:03, C shows 12:02, and D shows 11:06 therefore, max time is for B

62) Falling height is proportional to square of the time. One object falls 64cm in 2sec than in 6sec from how much height the object will fall.
Sol) The falling height is proportional to the squere of the time.
Now, the falling height is 64cm at 2sec
so, the proportional constant is=64/(2*2)=16;
so, at 6sec the object fall maximum (16*6*6)cm=576cm;
Now, the object may be situated at any where.
if it is>576 only that time the object falling 576cm within 6sec .Otherwise if it is situated<576 then it fall only that height at 6sec.

63) Gavaskar average in first 50 innings was 50. After the 51st innings his average was 51 how many runs he made in the 51st innings
Ans) first 50 ings.- run= 50*50=2500
51st ings.- avg 51. so total run =51*51=2601.
so run scored in that ings=2601-2500=101 runs.

64) Anand finishes a work in 7 days, Bittu finishes the same job in 8 days and Chandu in 6 days. They take turns to finish the work. Anand on the first day, Bittu on the second and Chandu on the third day and then Anand again and so on. On which day will the work get over?
a) 3rd   b) 6th   c) 9th   d) 7th
Ans is d) 7th day
Sol) In d 1st day Anand does 1/7th of total work
similarly,
Bithu does 1/8th work in d 2nd day
hence at d end of 3 days, work done = 1/7+1/8+1/6=73/168
remaining work = (168-73)/168 = 95/168
again after 6 days of work, remaining work is = (95-73)/168 = 22/168
and hence Anand completes the work on 7th day.(hope u understood.)
