Question 14 - Quantitative Reasoning Practice Test for the GRE

Bob looked at the type of food that 150 animals ate. The pets under the “Others” category consume 3 kinds of feed: Feed A, Feed B, and Feed C.

A total of \(\frac{2}{3}\) of the pets in this category consume A, \(\frac{1}{3}\) consume B, and \(\frac{1}{3}\) consume C, with some of these pets consuming mixed types of feeds.

If \(2\) pets feed on both A and B, \(1\) pet feeds on both A and C, and no pets feed on all three, how many pets exclusively feed on each of the brands (A, B and C)? Use the Venn diagram in the “Reading Aid” attachment.
