How many positive integers, from 2 to 100, inclusive, are not divisible by odd integers greater than 1?
Pick:	A) 5	B) 6	C) 8	D) 10	E) 50

Rationale: the no will be of the form 2 ^ n to achieve this . since any other form will have odd no in the prime factorization . hence we need to find solution of n for equation - 1 < 2 ^ n < 101 . 2 ^ 6 = 64 , 2 ^ 7 - 128 hence n can take values from 1 to 6 . hence answer : b
Answer: B
