2) technical test 75question in 40min

it was a very tough test i hav given test of 6-7 companies but csc test was toughest
ther vr linear equations questions wich vr not at all easy
questions on sets
-permutaion combination
-arrangement logical ques
– distance speed ques
– time question

-ques like 90% of 1 litree milk and 60% of 40 litre water result in 67% mixture so wht is compostion of milk in litres?

-ques like f has pririty over h and g has priortiy over i so now 4-5 ques based on this

-length is increased by 5 and breadth is decreased ny 10 thn total is 200m and whn length decreasd by 5 and breadth increasd by 15 thn total is 75 m, fing length

– os question on context switch and sytem call

– microporcesor ques like result of 2 input , 1 o/p line and three annd gates is (nand)

– which gate need to combine with or gate to make nand gate

– transfer RO to local and local to RO and shift RO 3 timed thn local to RO so result is

– some instruction were given and u hav to find resultanf values of flags

– some instrcution was given find output shift 2 times right to 80008ff

– atomicity definiton was given and u hav to tell wich property it is(atomicity)

– questions vr given fill in the balnks three places (placemnt,replacemnt,replacment) order was correct

– wich normal from shld be saticsy to hav bcnf and one more condition was given

– som ques of physics given resistance and volts use so u hav to tell output (low voltage or high voltage or??)

– wich sort take o(n^2) time

– some prog given outer fro loop from 1 to n and inner frm 1 to k so time is

-right output of preorder traversal som tree was given
