Ok so there are 10 people in the store and 5 leaves the store and 3 goes to the bath room how many are there left

assuming the 3 in the bathroom are still in the store, then there are 5 left, right?

Or, maybe 3 of the 5 who left went to the bathroom. Did they come back into the store, or is there an outhouse, so 5 are still left?

If you want a meaningful answer, ask a meaningful question.
