**Analytical**

- There are four captains a b c d e and their first mates m n and o ,not necessarily in order, ant they have to address a meeting such that each of the captain is followed by his first mate, conditions were given and questions were asked accordingly.
- The are five ways to reach city x to y, if we have to make a trip from x to x fives times….. (it a reasoning problem- i don remember the remaining part)

3. find X such that 2^x is highest factor in 12^10

a) 12 b)16 c)20) d)24

*Answer*

In 12 factors relating 2 are = 2^2 *3 so in 12 ^ 10 there should be 2 *10 = 20 hence x=20(c)

4. In which of the following equation K is consistent?

a) x+y=1

b)Kx+y=2

c)x+Ky=3

d) ??

5. Find log 9 base 8 + log (1/7) base…… +log…+log… =???

6. Find the transition in the two figures? a)x1=-1,y1=1 b)x1= – |1| y1 =1… …. ….

7. Find the transition in the below figures

a)x1=-1,y1=1

b)x1= – |1| y1 =1…

….

….

8. If AAHAAH / JOKE = HA what is the decimal value that relates them?

a)27

b)23..

…..

……

9. If 7x+11 / x^2 +2x +15 = ….Huh?? fixed x and y ..

………..

…………

**Basic concepts of C and OS(13 qs)**

- Union ans strut based program.. predict the output
- Bankers algorithm is used for ………….
- Number of nodes in a binary tree…..

Most of th questions are like predicting the output.

**Basic concepts of networks(15)**

Basic network questions, quite easy,

- subjective(10)(No Negative marking in this section alone)
- state the OSI layers in order
- distinguish between binary tree and graph
- which can be chosen for multimedia application ? why?
- write a program for factorial, such that we get inputs from the user.
- what is priority inversion.
