I have answers for Q/A paper. For Q/C you should try for answers. IIT Roorkee 1.8 65 .... The logic behind this question was that the sum of the digits were 8 11 14 17 20 .. the anwer was the number that contained 23 as the sum check for the number. 2.(x-a)(x-b)(x-c).....(x-z)=? ans. none of these 3.unscramble the word.. the word is parachute a four letterd word before the following words code,box,haste,..... 5.(be)2=mpb ans...m=3 6.a figure was given find the number of four sided figure ans.25(check) 7.2 questions were on passage...u would be asked to order them to make out was of lizard another was regarding the russian politics. 8.repeated question.......(truck) data would be provided... check out in the papers of the previous years papers(3 questions on these) 9. XRT computers...passage.. that was very simple u can easily do that.(3 questions). 10.3 ladies 2 men 4 children 3 sections in hall......(passage) (3 questions) u can easily do this as well 12. two questions on data sufficiency. 1.find out the whole sale price a.a discount of 10%was given to get the profit of 10%. b.the selling price was 50 dollars 2. commissioned employee.........(i don't remember that exactly). HCL (or) HCL Perot Systems (HPS) (or) HCL-CISCO section 1 In this section there are mainly questions based on C language like find the errors in the program and what is the output of the following program. some question i remember are 1) int i=10; printf("%d %d %d",i++,i++,i--); there is one or two more question on increment operator 2) Two question on redirection operator(>>)
3) int i=10;
printf(“The value for i is %d”,i);
4) one question on structure and u have to fine the error in the syntax
5) int a=10,b=33;
printf(“%d %d”, a,b);
6) int *a;
int (*b)();
printf(“%d %d”,sizeof(a),sizeof(b);
7) # define SQR(a) (a*a)
void main()
printf(“%d”, SQR(5));
8) And in another question # define directive is declared in the main() function of the
program and u have to predict the output of the program.?
9) what is the time complexity of bubble sort (Ans: O(n^2))
10) what is the preorder traversal of the folowing tree some tree is given (this is not the actual tree given in the paper only idea)
11) x=2,y=6,z=6
12) What is the size of the address bus and data bus in 8086?
13) address of IVT in 8086?
Section II:
1) some 6 guys are there A,B,C,D,E,F(say) and u have to adjust in the row.
and some statements are there like A & D can’t be adjacent
E,A have one vacant area in between.. like that and there are 5 questions are based on that?
2) this one is tricky .. there are two groups . one is many brothers can mary one sister of
other group. and second is many sister can mary one brother of other group
and some statements are there like V & U is father of S, X is the only grandmother of
S …like that..
And there are 6 question based on that..
3) and rest of questions are purely aptitude & quant based.
like there are two questions on coding if MYSORE is code like MEMEME
then how TAMILNADU is coded?
