If q is a positive integer less than 17 and r is the remainder when 17 is divided by q, what is the value of r?

1- Q>10

2- Q= 2^k, where k is a positive integer











OA is C.


Statement 2- Q can be:

k 2^k Q 17/Q R<--Target
1 2^1 2 17/2 1
2 2^2 4 17/4 1
3 2^3 8 17/8 1
4 2^4 16 17/16 1


So why do we need Statement 1?

you are right; the answer should be (b), not (c).
