Given matrix A and I(identity matrix). Find matrix B where AB=I.

y=log(sinx), find dy/dx.

B is 8 Km East to A, C is 6 Km north to B, D is 16 Km east to C and E is 12 Km north of D, Find distance between A and E.

A train is moving with the velocity of x Km per hr. it crosses a station of length y Km in

z meter per second. Find the length of the train.( here x, y and z are given)

The ratio of length of a rod and its shadow is 1/sqrt(3). Find the angle of elevation.

Find LCM 120 and 60.

4(144)8, 3(x)7 find x.

For the given fig ,find the angle x. All angles are in degree.

limit x->¥ [(x+6)/(x-1)][(x+6)/(x-1)]

>>>> There are 20 such questions. Questions are very easy.

Section-2 consists of some questions from microprocessor, digital electronics, one question on turing machine(the question was very long) and some questions on C(some what tricky-but solvable if enough time is left)

Some questions which I remember are-

Find sqrt of 113 upto 3 decimal places.

20 bit address bus can address how much memory

find 2’s complement of 111001001

Conver 100011 in decimal

(120)10 to (x)7

To represent A to Z and 0 to 9 how many bits are required. Assuming all the characters requires equal bits.

210 =……Kilo byte

A op B = XXXX00XXXXXX0XXX

Find B and op, where op is a logical operator and X=don’t care

To add 16 bits numbers how many full adders and half adders are required.

A full adder has how many input lines.

Find Y

#define count(x) sizeof(x)/sizeof(x[0])
what count(x) does?

X=24, Y=16
X^=Y

Y^=X

X^=X

Y^=X

Find value of X and Y( the exact question may be some what different)

#define inum 53268

While(……….)

{

inum=inum &(inum-1);

Write a program which will accept only ‘0’ to ‘9’, ‘+’, ‘-’, ‘#’ characters as inputs.

In a circuit of gates all gates are controlled by a single ……………

How many inputs are there in a NOT gate
