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?
The Farmer in the Deli sandwich shop sells two kinds of sandwich: tuna melts and veggie melts. Each customer buys exactly one sandwich. If there were 300 customers yesterday, what fraction of veggie melts sold yesterday were bought by female customers?
(1) 1/2 of all sandwiches sold yesterday were tuna melts, and 1/3 of all customers yesterday were male.
(2) Yesterday, twice as many tuna melts were bought by females as there were veggie melts bought by males.
