Virtusa Paper
2 Marks * 5 Questions = 10 Marks
ANALYTICAL
1) 1, 2, 3, 2, 5, 6, 7, 8, 3, ____ What is the next number in the series and he asked the reason also?
2) There are 4 coins, you have to arrange them in a 2 rows so that each row should have 3 coins each and reason for that?
3) Find the odd Word out? ALPHA, DELTA, SIGMA, OMEGA
4) Find the odd word out? DEAF, REST , BACK, HELD
5) In Chess Board, how many knights can u arrange so that no two knights will attack each other? and He explained the problem.. using mathematical positions of the knights like (x+1, y), (x+1, y+1) and so on upto 8 points in which way the KNIGHT travels in the CHESS BOARD?
4 marks * 5 Questions = 20 marks
1) if SATURN
URANUS
---------------
PLANETS
In this Each LETTER represents a single DIGIT. Now you have to find atleast 3 digits. no need to find all DIGITS?
2) 1, 2, 3, 25, 50, 75, 100 using these digits once and only once with basic operators you have make 81?
3) There are 11 Huge boxes, 8 large boxes, 8 small boxes. Now there is a table first someone put 11 Huge boxes on the table and in some of them he added 8 large boxes, and then he put small boxes in large boxes. Finally he has left 102 boxes empty. Now How many large boxes were kept in huge boxes and small boxes were kept in large boxes.
(Just similar to this.. question… not reminded clearly… check it out….)
Ans: Key Steps:
4) He gave one series based on the last 3 letters of the SOLAR PLANET SYSTEM keeping tow of them blank and asked us to find them. it was very easy. SUN, ARS, URY, ____, …______, UTO
Ans: RTH and one another (EARTH and some thing)
5) A Problem on ROPES… There were some ropes that are of different lengths and different thickness. Each can burn in 12 minutes individually. If we are given 9 minutes as ELAPSED TIME how many ropes can be burnt in that time. (Just Similar to this…. Check out with some other friends). Ans:
15 Marks * 1 Question = 15 Marks
WRITING SKILLS
(This is the important and may be most important eliminate process in Virtusa)
1) Write the advantages of "all the rivers linked together in India" and gave one note that this should be published in Computer Magazine. (May be his intention is to explain the Topic using Computer Words)
10 Marks * 4 Questions = 40 Marks
PROGRAMMING
(Note: You may use language of programming to write the following codes)
1) Write a program to print all the four digit numbers whose squares must have all the even digits.
2) Write a program to print the pyramid up to the passed integer value.
1
2 3
4 5 6
7 8 9 10
11 12 13 …
If we pass the value 13 it should print like the above (no need to print the 3 dots)
3) In a certain DATABASE we had to store the TIMESTAMP for each record. Is there any way store in an efficient way to store (Memory)? The Time stamp has the following fields. Year, Month, Date, Hour and Minutes. Discuss the design such DATASTRUCTURE.
4) Write a function which takes one string S, one character X, one more Character Y which should return the longest substring in the String S, which starts with the X and ends with Y?
15 marks * 1 Question = 15 Marks
1) For the problems like SATURN + URANUS = PLANETS (As Explained in the above) which were written in cryptography. Write a program to solve such situations. The most generalized way.
All the Best Friends……
I have attended 4, 2 marks quesitons, and 3 four marks questions. and I have written the Topic basing on Internet. and I wrote first 3 programs and was trying to write the 4th program.

DATE OF TEST : 9 June 2004
Pattern: (No multiple choice Qns) --------
4 Sections.
1.Analytical Reasoning (12 qns.) ================================
(we have to write reasons for the answer.)
( I don't remember exactly what they had given.I am putting it in my own words)
1) x1 peach + y1 plum = z1 apple x2 peach + y2 plum = z2 apple (x1,y1 .... z2 are integer values) How many peaches make one apple?
2) 100,100,102,106,112,120,____
3) which is greater ? Product of all Bradman's first class scores or Sum of all test scores of Sachin.
4) U r provided with 500ml and 300ml jar(it has no markings).
a) u have to measure exactly 100ml.
b) u have to measure exactly 200ml.
5) Using four 4's u have to make 1 ... 10.
( for eg. 1 = (4/4)*(4/4) 2 = ? . . 10 = ? )
6) student,canopy,thirst,... are the words given. u have to group the words using the following words
1)Master
2)Teacher
3)Deft etc..(i don't remember some of words)
7) U have to cut a Pizza using 7 st. lines(wit out rearranging) and u have to obtain maximum number of pieces.
( Give generalised solution..)
8) U have to cut a Cylindrical cake of diameter 32 cm and height 20 cm in to 12 equal pieces.
9) In a village there r 2 groups.
1) Knight -> always tell true
2) Knave -> always tell false
Mr.X met a man of that village(u don't which grp he belongs) and questioned "Tell me whether u r knight or knave ?"
Reply: "i cannot tell u and left that place"
Find which grp that man belongs to?
10) obtain 277 from 3,25,50,65,100.use 4 arithmetic operations only.
11) 1#2=x ,2#3=y, 4#4=z
4@14=a, 5@15=b, d@e=f
( i don't remember values for x,y,z,a,b,c,d,e,f)
find (2#4)@5= ?
12) (i don't remember what they had given.) It is just example for that question,
CODE is encoded as DGBF
READ is encoded as JHNV
2. Essay(General).
==================
(Topic given: India should spend money on Atom bomb and Rocket OR for the welfare of poor.)
3. Problem solving.
===================
(Problem statement: How will u determine number of Petrol bunks in Madras.)
4. Programming.(4 Qns)
===============
( we can use any Programming Language for coding)
a) They had given one function ,we have to find it what it does and also problem in the fn. and how to overcome it.
double what( double z, int y)
{
double answer;
while( y > 0 )
{
if( y%2 == 1) answer = answer * z;
y=y/2;
z=z*z;
}
return answer;
}
b) They had given one Pseudocode.We have to find bug in the pseudocode.
I don't remeber the pseudocode fully.But the function of pseudocode is "To make a Robot to fetch a tumbler of water"
c) write a program to print all Armstrong numbers,
(abc=a^3+b^3+c^3)
(for eg. 153=1^3+5^3+3^3)
d) write a function witj the following conditions,
1)It should have one integer parameter.
2)If the value passed is -ve, return -1.
3)If the value passed is a perfect square, return root of that number.
4)If the value passed is a not a perfect square, return that number itself.

DATE OF TEST : 2004
------------------------------------------------------------
Virtusa Paper consists of 3 sections .
1. Analytical
2. Analytical Writing
3. C-Programming
First when v clear the cutoff of Analytical section,only then other sections r evaluated.So,Don't waste time by spending much time on Programming.
Analytical Section:
-------------------
Analytical Section consists of Vocab. ( pick the odd one out ) and also some codings like ( ALPHA z coded as BETAH , DELTA z coded as GAMMA, then how z ETA coded ? .. this one .. i have framed it :) ) .
This part z a bit difficult one. So, my advice z don't think much about these.
Along with above two categories, there shall be PUZZLES in this section.In the recent paper i attended,i got the following questions.
1.Volume of a LARGE SPHERE z ( pi * # ) .
Area of it z ( pi * & ) where '#,&' r four digit integers.
What z the value of the radius ?
( Along with answer , v have to write approach).
answer: may be 22
2.In howmany ways can a rectangle can be cut into 4 equal parts.
3.Given 1,2,3,25,50,75 and 100 .. Using each number "one and only once" and using arithmetic operators, write 383 in terms of the above given numbers.
answer: 383 = ( 100 + 2 ) * 3 + 75 + ( (50 * 1)/2 )
4.A tougher question of above. given 1,2,25,50,75,100 .. write 383 in terms of the given numbers.
5.Given following sequence,find the how the sequence is generated.
2 -> 1,4,9,6,5,6,9,4,1,0
3 -> 1,8,7,4,5,6,3,2,9,0
4 -> 1,6,1,6,5,6,1,6,1,0
answer : the sequences r nothing but the UNIT digits of square(x),cube(x),power4(x) where x = [ 1 ... 10 ]
6.Knights always tell TRUTH.
Knaves always tell LIE.
U r a foreigner to that place
and U have met a person and he replies "I am a knave " .
What can u infer from his statement.
answer : nothing can be infered from his statement.
7. using 4 fours and arithmetic operations write from 1 to 10
3 = ( 4 + 4 + 4 ) / 4
4 = ( 4 - 4 ) * 4 + 4
5 = ( 4 * 4 + 4 ) / 4
6 = 4 + ( 4 + 4 )/4 // 4 + 2
7 = ( 4 + 4 ) - ( 4 / 4 )
8 = ( 4 + 4 ) * ( 4 / 4 )
9 = ( 4 + 4 ) + ( 4 / 4 )
10 = ( 44 - 4 ) / 4
I forget the two more questions.
Analytical Writing :
------------------
This section has two questions only.
1.General topic. ( Don't forget that v have to just write one page only .. not an essay) ( So,write the points directly )
For us they gave topics
Is it necessary for to HOST AFROASIAN GAMES ?? Why can't it spend that money for the welfare of poor ?
OR
Can India have better results if the current for of govt. is changed to PRESEDENTIAL FORM OF GOVT. ( like USA ) .
2.He gives a highly impossible possible and asks to give a solution.( To check ur innovative ideas :) )
For us,
Suppose u have suddenly changed to an ANT.U know human's abilities,but u have forgot their language.How can u make urself to convey ur BELOVED that u have been changed to an ANT.
Programming :
-------------
This section consists of 4 questions.
Out of 4, for 3 questions v have to write code.
The last question shall be ..
they shall give some code and v have to write whether the code is correct one r not ..
if not correct , where the modifications show be done. and also v have to write what that CODE IS DOING.
