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.
