    apti/quant/logical
    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

    APTITUDE/QUANT/LOGICAL TEST QUESTIONS
    -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

    -a>b>c so wich is tru
    ab>ac or a/b>b/c or som more options

    -6 girls and 6 boys, all boys and all girls will sit together so no of possible ways

    technical ques
    -os
    -dbms
    -ds
    -n/w
    -microprocessor(806139...)
    -java
    -c c++ 

       
    TECHNICAL WRITTEN TEST QUESTIONS
    - wht is piggybanking used for (acknowledgement)

    - wht combines router and bridge
    (hub/brouter)

    - tcp/ip is wht conection oriented or conectionless

    - X.25 protcol is at wich layer

    - wht is superkey (primarykey+attribute)

    - wich join will u use to hav null values (outer)

    - query was given find join type
    select customer.is and order.is and name from customer, order
    where cutomer.id= order.id (natural join)

    - wich follow binary tree property

    - som code of java given find no of dangling pointers

    - linked list a->b and b pt to itself so wht type of linked list (infinite)

    - which line is wrong abt linked list
    (circular list can be only implemented in doubly linked list)

    - 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
    (RO=local)

    - 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
    quicksort

    - some prog given outer fro loop from 1 to n and inner frm 1 to k so time is
    O(nk)

    -right output of preorder traversal som tree was given

    - wht r abstract data types
