Nice overview of GMAT Math topics. Don't know whether this has been uploaded before...

Question on the Set theory example

by r_walid » Thu Jan 22, 2009 2:55 pm
Hi, thanks for posting this great document.
I have a question in the set theory example.
When it says: "If 10% of the red toys are small" it is NOT saying that 10% of the total number of toys are Red and small, it's saying that 10% of the red are small, meaning that in the table below, you should not put R+S as 10% but rather 40% * 10% and fill the table as follows. am i right or am i missing something?


In a certain production lot 40% of the toys are red and remaining toys are green. Half of the toys are small and half are large. If 10% of the red toys are small, 40 toys are green and large. How many of the toys are red and large?


Large Small Total
Red 30 10 40
Green 20 40 60
Total 50 50 100
