Each week Manhattan GMAT posts a 700 level GMAT question on our blog and follows up with the answer the next day. Are you up for the challenge?
At a particular moment, a restaurant has x biscuits and y patron(s), with x ? 2 and y ? 1. How many values of y are there, such that all the biscuits can be distributed among the patrons, with each patron receiving an equal number of whole biscuits and with no biscuits left over?
(1) x = a2b3, where a and b are different prime numbers.
(2) b = a + 1
