Please help me with following question.
Quantity A
Qunatity B
Simplifying the quantities I come up with quantity A=10 rootover(2a) and quantity B=15 rootover(2a). But value of A is not specified anywhere. If value of a is negative then part inside rootover can be undefined. So what should be the answer of this quantitative comparison. B or D.I guesst it should be D. But Kaplan answered it B.
