Q Is b greater than 1?
(1) b^2 is greater than b
(2) b is positive
Correct Answer: Together (C).
I am leaning towards (E). Can you explain in detail why C is the correct answer and the strategy behind it. I would really appreciate the help!

b(b - 1) > 0 implies b < 0 or b > 1
Hence, b may or may not be greater than 1; NOT sufficient.
(2) b is positive implies b > 0.
Hence, b may or may not be greater than 1; NOT sufficient.
Combining (1) and (2), clearly b > 1; SUFFICIENT.
The correct answer is C.

1) If b=2, then b^2 > b, and if b=-2, then also b^2 > b. Insufficient.[email protected] wrote:Q Is b greater than 1?

2) If b=0.5 the b^2 < b, and if b=2, then b^2 > b. Insufficient.
Combining 1 and 2, We can say for sure that b>1. Sufficient.
(For any number b such that 0<b<1, then b^2 < b, and if b=1, then b^2 = b. Therefore if b is +ve and b^2 > b, then b has to be greater than 1)
