This simple math puzzle is going viral again, and it’s tricking everyone.Here is the question:
“You’re in a room with 70 people. 30 people leave and 15 return. How many people are in the room now?”Most people rush to do the math: 70 – 30 = 40, then + 15 = 55. It seems obvious, right?But read the first sentence very carefully.It says:
“You’re in a room WITH 70 people.”That means you are ALSO in the room. You are not counting yourself. So the total number of people at the start is actually 71, not 70.So the correct calculation is: 71 – 30 = 41, then 41 + 15 = 56.Some people argue the answer is 55 if you count yourself as part of the 70, and that logic also makes sense.
That’s why this quiz creates so much debate.It’s not really a math test. It’s a test of how carefully you read.This is a fun brain teaser to challenge your friends and family. No calculator allowed!What was your first answer? 55 or 56?
