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:

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.


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.

Virtusa Paper consists of 3 sections . 1. Analytical 2. Analytical Writing Freshersworld.com 3. C-Programming
First when v clear the cutoff of Analytical section,only then other sections are 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 givennumbers. 5. Given following sequence,find the how the sequence is generated. 2 -> 1,4,9,6,5,6,9,4,1,0 Freshersworld.com 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 ) Freshersworld.com 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 ? ORCan 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.
