Virtusa Paper.
-------------
section-A (5*2=10 marks)
----------
1.Pick out the Odd word out:a. CDBFE , JIHKL ,OMQRP ,WUXVY
2.Neem,Team,Starter,Commit.Ans: Reason:
3.101 , 101 ,107 ,119 ,137 ,_____
section-B (4*5=20 m)
-----------
1.Arrange the numbers 1 to 9 in any way to obtain the sum 100.a)Use nos 1 to 9 in the natural order of occurance.b)use all the 4 operators and parathesis.
Ans:((1+2)/3)+4+(5*6)-7+(8*9)
2.There are animals like goat,sheep and cow.one goat and seven sheeps eat as much as one cow eats.Also, three goats and one cow eat as much as eleven sheeps.If there is some fodder which is sufficient for a cow for three days,then for how many days will that fodder feed the goat.
3.There is a sphere.The volume of the sphere is (pi*theta).and the surface area is (pi*gamma).where theta and gamma are five digit numbers.find the radius of thesphere.
section -C (15 m)
-----------
write a brief account on the measures to be taken to against the US law of stopping outsourcing to India.
section -D (4*10=40)
writa a prg in any language:1. Wirte a function to accept a number 'n' and
a)if n is negative then return -1.
b)if n is postive and perfect number then return sqrt(n).
c)if n is positive and not a perfect no. then return n(n+1)/2
2.Write a prg to print in the format
1
2 2
3 3 3
4 4 4 4
5 5 5 5 5.
3.double fn(double z,int y)
{
double a =1.0;
while(cond)
{
if (y%2==1)a=a*z;y/=2;z*=z;
}
return a;
}
what does the function do an how do you eliminate the shortcomings of the function.
4.Write a prg to generate the next number (ex:143=1^2+4^2+3^2=26)repeat this sequencetillyou get 1 or 4.
B) (15 m)
Write a prg to accept two time stamps in the given format
HH:MM:SS
using apropriate datatypes and find the difference between the time stamps in seconds.
There were 3 sections:(In which they tested 4 skills)
Analytical&Logical skills
Programming skills
Writing skills
All the 4 skill tests are fully brain teasers.
The duration of the test was 2hours,and the L&A Reasoning has a minimum cutoff u should clear that to evaluate ur other sections.
The questions are as follows (These are not in serial order and the information may not be accurate, when specified)
SECTION 1 (Analytical and Logical)
1.1 2 3 2 5 6 7 8 3 find the next term in the series
Ans: Reason:
2.How can u place 4 coins in 2 lines so that each line should contain 3 coins
Ans:I wrote, it maynot be possible
3.Find the odd word
ALPHA
DELTA
SIGMA
BETA
Ans:I think it is Delta, Reason: as it has specific meaning(addition)and others don't have such meaning,just used for representation purpose.
4.There was an addition given as follows
SATURN + URANUS = PLANETS
the solution is not encoding the entire problem but to find coding for 3 alphabets
Ans: Key Steps:
5.There was a set of words given as follows
SUN,MER,VEN,---,...........,SAT,---,NEP,PLU
(I don't remember exactly but, all are the names of planets in solar system with notation of each planet using 3 letters)
The question was to find out the appropriate words in the given blanks
***SOME CHOICES WERE GIVEN***
Ans: Reason:
6.How can u get 81 using the digits 2,3,25,50,75,100 only once using any of the arithmatic operators
Key Steps: 50+(100/75*3)+25+2
7.(This is a real sitter, takes a long time) A man have some three types boxes viz Huge,Large,Small He took 11 of huge boxes and put on a table.And at random he has taken some of them and placed 8 large boxes in each of the boxes.And after that he has placed 8 small boxes in some large boxes at random.By the end if he found 102 boxes empty, how many boxes are there on the table?
Ans: Key Steps:
8.If u have a large number of Knights and a chess board.The problem is to find the way of arranging the Knights on the board so that no Knight attacks the other. (He has given mathematical relations that represents how a knight can move on the chess board as we know it as 'L', i'm not giving such stuff)
Ans: Key Steps:
9.You are given a bunch of threads each having differing length.No two thereads have same thickness and no thread has same thickness all its length. But it is certified that any thread when lit burns itself in exactly 12 mins. The question is you are asked to find an elapsed time of 9 minuites.How can u find it out and how manythreads do u want for this?
Ans: Key Steps:
(I think most of the questions are covered here. But there may be a couple of questions left which i can't remember in this Analytical and logical reasoning, OK)
SECTION 2 (Writing)
The topic to Write was on "Connecting the rivers in India".
SECTION 3
You can write the programs in this section using any programing language
3.1)
1.There was a pyramid given as follows
1
2 3
4 5 6
7 8 9 10
11 12 13 ...
The three dots are given as a part of the specification. The above pyramid is to be printed when input number 13 is given. Write a program to print the above pyramid.
2.Write a function which returns a substring in the string 'Sigma' (character given)which starts with 'Alpha' and ends with 'Thita'
3.You have a job in which you have to take time stamps and store them. So Write a datastructure that can minimize the storage requirements of Year,Month,Date,Hour,Minuite.
4.Write a program to find the four digited numbers, which are perfect squares, and all the digits in that number are even.
(i think there is another program given which i don't remember)
3.2) THIS CARRIES 15 MARKS
The types of problems such as prob #4 from the section 1,
(SATURN+URANUS=PLANETS) are called cryptorithms or alphabeticalcoding. Where an alphabet is assigned a code so that the problem is to be solved using given summation. Write a program to solve such questions, which prints the letter and its corresponding digit that satisfies the given addition.
This is the paper for virtusa about 450 of us attende the At out of which 43 cleared for the GD. then they had interviews - very less technical n more of communication skills. out of 43 only 22 cleared went for interview. Finally 11 were shortlisted only 2 from r college others from nearby colleges. once u have cleared the AT the selection is very simple.
in the AT they r only tesitng ur approach so give proper reasons for the answers. questions r easy.some questions i remember r
1.A 4 kg cuboid is reduced to 1/4th of its original dimension.what will be the new weight?
ans: 62.5 gm
2.A bank pays 4% simple interest compunded annually.x deposits 100$ at the beginning of each yr then what will be the amount at the end of the 5th yr.
ans: 563(not sure)
3. what will be the growth of a tree whose current height is 60 inches with a growth rate of 10%, at the end of 3 years.the value rounded upwards. ans: 81(not sure)
4. a frog lying in a 30 feet well climbs at the rate of 3ft/hr but slips 2ft each time.how many hours will it take for the frog to climb out. a)26 hrs b)27 hrs c)28 hrs d)29 hrs
ans: 28 (i think)
5. a water lily grows at a rapid rate filling the pond in 20 days.how many days will it take to fill the pond if we start with 2 such lilies with same growth rate.
ans: 19 days
6. 20 people go trekking uphill.30% get frostbite n leave the 1st day.of the remaining 2 get sprain n giveup.of the remaining only half of them make it to the top.how amny reached the top.
ans: 6
7. given a liquid n two containers of 400ml n 600 ml respectively can u measure 500ml.if yes explain.
8. candy bars r distributed to children 3 to each except the one at the end who got 2.if only 2 were given to each then 8 candy bars were left.what was the original no of candy bars.
ans:26
9. many rules r given n the valid statement is asked.
ans: the last option.
10. many designs r given n the next possible one is chosen.very easy to do with little imagination.
11. numbers in a sequence n encrypting letters also was there.
C section-
3 questions were given but better to attend 2.
1.when a user inputs values, if it is even perform a divide by 2, else perform n*n-1 and store them in a sequence.the output must be the largest power of 2 in the given sequence.
2.write a prog to generate pythagorian triads of the form a^2+b^2=c^2.eg3,4,6. the sequence should not repeat by changing the order of the numbers like 4,3,6.
3.a prog is given n we have to check if legal or not. if not correct it or describe its working.the prog looked like a fibonacci generating sequence.
