Q1: r = s^3#6 ( i.e--- s raised to the power 3#6)

and s^# = 10 ( i.e---- s raised to the power # )

COLUMN A: #^3

COLUMN B: r/1000

The ans is C ( both are equal) plz EXPLAIN how????

By the way...no other information about " # " is given.!!!

Q 2 :

72.4=k(24+n/100)

n < 100

k+ n=?

the ans is 17....i did it after some long and tedious calculations

can somebody suggest a shorter method???

Q3: If one number is chosen at random from the first 1000 positive integers

,then what is the probability that the number is a multiple of 2 and 8?

I did this the simple way...a multiple of 8 would invariably be a multiple

of 2 also....so the ques would be to find multiples of 8...since every

8'th number will be a multiple of 8 ...so the ans is 1/8

but this approach may not be instrumental in solving some other ques.

SO, PLEASE SUGGEST SOME DIFFERENT APPROACHES TO THIS QUESTION.
