Hello,

This is part of a problem in one of GMAT's official books:
"Of the 84 parents who attended a meeting at a school, 35 volunteered to supervise children during the school picnic and 11 volunteered both to supervise children during the picnic and to bring refreshments to the picnic."

This is a part of the solution:
"Out of the 35 parents who agreed to supervise children during the school picnic, 11 parents are also bringing refreshments, so 35 – 11 = 24 parents are only supervising children. "

Does this make any sense? They are clearly using the word "and" which implies you would add 11 to 35 which would make 46 parents.

Thanks
