This simple-looking puzzle says there are six people in a room and two of them leave. How many people are still in the room?
The answer is 4.
If six people are present and two walk out, subtract those two from the original six: 6 − 2 = 4.
Some riddles hide a trick in the wording, so people often overthink questions like this. But in this case, the straightforward reading works perfectly. The question asks how many people remain in the room after two leave.
That leaves four people still inside. The main challenge is resisting the temptation to invent an extra twist when the information already gives you everything you need.
