What is the greater of the two numbers whose product is 2688, given that the sum of the two numbers exceeds their difference by 64? Choose the correct choice:
A) 84	B) 104	C) 110	D) 72	E) of these

Rationale: "let the greater and the smaller number be g and s respectively . gs = 2560 g + s exceeds g - s by 64 i . e . , g + s - ( g - s ) = 64 i . e . , 2 s = 64 = > s = 32 . g = 2688 / s = 84 . answer : a"
Answer: A
