1. 1 2 3 2 5 6 7 8 3 find the next term in the series
2. How can u place 4 coins in 2 lines so that each line should contain 3 coins Ans:I wrote, it maynot be possible
3 Find the odd word
Ans:I think it is Delta, Reason: as it has specific meaning(addition)and others don’t have such meaning,just used

for representation purpose.(i think so)
4. There was an addition given as follows
the solution is not encoding the entire problem but to find coding for 3 alphabets Ans:Key Steps:
5. There was a set of words given as follows
(I don’t remember exactly but, all are the names of planets in solar system with notation of each planet
using 3 letters) The question was to find out the appropriate words in the given blanks
6. How can u get 81 using the digits 2,3,25,50,75,100 only once using any of the arithmaticoperators
Key Steps: 50+(100/75*3)+25+2
7. (This is a real sitter, takes a long time) A man have some three types boxes viz Huge,Large,Small He took 11

of huge boxes and put on a table.And at random he has taken some of them and placed 8 large boxes in each

5 .Analise the Programe
int x=1,y=1;
while( (x > 0) && (y > 0) ){
x += y;
y += x;

6 .Start from a random number, generate a sequence such that if number is odd multiply it 3 and add 1. If number

is even, divide the number by 2. This Sequence will always cyclic with 4, 2, 1. In this sequesce, find the maximum

power of 2 generaged in the sequence and print only the power, not the sequence.
7. Start with a random 2 digit number, The series is generated by multiplying the number by 2 and placing the last 2

digits as the next number. Series continues until one of the element repeats.
8. write a function maxsubstring(str,alpha,theta) str is the source string and have to return maximum sub string

which starts with alpha and ends with theta.
