Just looking at a brain busters site (http://www.justriddlesandmore.com/Brainbusters/BB%20archive%2026-50.html), I came accross this one:

Stopping along the trail to rest, Judy saw that one-third of the rest of the group from the Girl Scouts was behind her and three-fourths were ahead. Not counting Judy, what was the total number in her group?

They say that the answer is xyz (check the link if you wanna do it yourself), but the problem I see is that one third is 33.33% while three fourths is 75%. That adds up to 8.33% more than the 100% of all girl scouts there. Am I right in saying that they are wrong, or is some maths guy gonna come and spoil my party?

Yes it is wrong.

1/3 of the remainder of the group plus 3/4 of the remainder of the group added together results in the number that includes her, but the question clearly states that it doesn't.
