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 the
sphere.
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 sequence
tillyou 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.(i think so)
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.
