Hi myself2014,

This is clearly not in the proper format to be a GMAT question. While this type of 3-group overlapping sets question is rare on Test Day it WILL NOT allow for people who aren't in any of the groups (in this case, people who "took none of the meals").

That having been said, I think that there are some typos/incorrect information in the question. What is the source?

GMAT assassins aren't born, they're made,
