Quote:
720 cents can buy 72 bananas. If the price of each banana is reduced by 1 cent, 720 cents can buy 72 + x bananas. If the price of each banana is reduced by 2 cents, 720 cents can buy 72 + y bananas.

When confronted with algebra in Quantitative Comparisons, attempt to solve algebraically for maximum efficiency. If 720 cents can buy 72 bananas, then each banana costs 720 ÷ 72 = 10 cents.
Then, if a banana were to cost 9 cents, 720 cents could buy 720 ÷ 9 = 80 bananas, which in turn means that x = 80 - 72 = 8. So, Quantity A = 8 x 2 = 16.
Finally, is a banana were to cost 8 cents, 720 cents could buy 720 ÷ 8 = 90 bananas, which in turn means that y = 90 - 72 = 18. So, Quantity B = 18.
Select Choice B.
