1) General Information:
Two seperate tests:
1. Technical(30 questions-30 minutes)- Separate questions for CS and EC.
2. Analytical(30 questions-20 minutes)

2)Technical Test(20 questions out of 30)
1) Graphics:Painters algorithm is used for...........
2) Graphics:Why is 'Lighting' operations done on World Coordinates?
3) Graphics:One more question
4) Some question on C External Variables.
5) How can you call a function written in FORTRAN from a C program ?
6) Normal question on pointer addition
7) Another question on pointer adition
8) A question on 64 bit OS's and Virtual Memory it will be having
9) Another question on 64 bit OS
10) A structure was given and it contained normal data as well as some bit-wise data.You had to
find the total size taken up by the structure



11) A big code with lots of pointers. There was a struct which contained 2 arrays. Then an array of
that structure was declared. The code used these structures and you had to find the values of a
variable 'j' at various points inside the code
12) A code which had some declarations of some data items. There were a couple of normal data
items(char,int..) and some pointers as well and a malloc call. You have to find the total memory
taken up in the stack(Hint:Pointers and all are allocated in heap, not in stack, so dont count
them).Also in most of these questions, they were specifying that the OS was 32 bit
13) A question on nesting of pointers. There was this pointer to a function which returned an array
of char pointers.....You had to give the exact definition of the function
14) Value of 2 particular variables in C(MAXINT and some other constant)
15)What do you need to do to open more than 10 files simultaneously in Microsoft Operating
System?
-change stdio.h/change CONFIG.SYS/compiler dependent
16) A question on Macro( consisted of something like CTRL&037)
17) Another question on Macro expansion
18) Yet another question on Macro expansion
19) UNIX question on 'who' output and then doing some other operation and then asking you whats
the output.
20) UNIX question on 'awd' operation.
3)Analytical Test(20 questions out of 30)
1) 101^100 -1 is divisible by.....
2) Question on boat ( stream velocity given...)
3) Train Question( Goods and Passenger train.. their speeds given..)
4) Pipe question (with leak at the bottom..)
5) Salary & Proportion problem
6) Another problem on Salary & Proportion
7) Age question-father and son



8) Another age question
9) Question onratios(Sachin:Saurav=Saurav:Rahul=3:2....together they scored some runs,you had
to find the runs scored by Sachin)
10) Angle between hands when time is 2:20
11) x^2 + 4 y^2 =4xy.Find x:y
12) A question on Arithmetic Progression(something like 5 times the 5th term is 8 times the 8th
term..find 12th term...)
13) A and B's work units given.They were together gievn Rs.720.When C joined,they together
completed the work in 5 days.Find C's wages
14) There was a circle.A square of max size was cut from it.From this square,a circle of max size
was cut.What was the ratio of this final size w.r.t initial size?
15) A runs 3/4th faster than B.One of them was placed some metres ahead.How far should the
finishing post be placed so that both of them finish at the same time?
16) Longest time one has to wait for next birthday?(366/365/4 years/8years)
17) Next no: in the seq: 7,11,__,19,23
18) Some question on steps...it was 10 ft high...an ant travelled upwards..and total time taken
19) Cricket-some data on runrate of the opposition being 15%....
20) Time & Distance..somebody was travelling along the circumference.
