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.
