Seven Rooms
This is a problem from the Math Olympiad for first- to third-grade elementary school students.
Twenty-eight children enter seven rooms labeled A through G at random, and based on five given conditions, you must determine which room has the most children and how many children are in that room.

However, if you check each condition one by one and perform the calculations, you can arrive at the answer.
The calculations themselves are simple, but the problem tests your ability to think logically and to derive equations from the given conditions.
