if A^2=B

is the value of A between 0 and 1?

1. b is between 0 and 1

2. a>b

puzzled i rephrased this and it got even worse.

Ans can not be A, it is B

(A) 0<b<1 so A can be -1<A<1
so insufficient

(B) A>B and A^2 = B so we know that A is a real fraction since only in case of a real fraction the square is less than or equal to the original value, meaning that A is 0<A<1

E.g. A = 1/2 and B=1/4
A = 1/3 and B = 1/9
