Q on boolean operator

There are basically 2 papers :

1. Technical (30 questions,30 minutes)
2. Aptitude (30 questions,20 minutes)

There will be different technical test for EC and CS

Ec :: digital ckt,op-amp,analog,communication etc
Cs :: OS,Sys-software,C/C++ etc

Apti is same for all :: Refer R S aggarwal
pipe and cristen,train and some other etc.

the selecion criteria for interview was top scorers

apti score...

Two seperate tests:

-Technical was conducted first followed by Analytical
-There was no negative marking
-There were no seperate question booklets.Everybody had the same one

-Technical test(for computer science) consisted MAINLY 'C' questions.And most of them were difficult ones.There were 3 questions from Computer Graphics ( Tata Elsxi is also into Multimedia Development,that may be the reason )

-Analytical test DID NOT HAVE ANY ENGLISH QUESTIONS.R.S Aggarwal's 'Quantitative Aptitude' would be very helpful here because there were questions asked from Numbers/Simplification/Problems on Ages/Profit and Loss/Ratio and Proportion/Time & Work/Pipes & Cisterns/Time & Distance/Problems on Trains/Problems on Boats & Streams /Area/Volume & Surface Area/Calendar/Clocks.So as you can see,they covered almost the entire book

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?

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?
