Riddle: There are 12 men on an island. 11 weigh exactly the same amount, but one of them is slightly lighter or heavier. You must figure out which. The island has no escapes, but there is a seesaw. The exciting catch? You can only use it three times.

It is both a real puzzle and a real question of intelligence. It is a good question that you can have fun with your family or friends. Let’s tell the solution step by step.

First, let’s divide 12 people into groups of 4.

As a second step, Let’s put 2 groups of 4 people on seesaw. If it is the same, the slightly lighter is in the 3rd group. If it doesn’t come in equal weight, let’s separate the lighter group. In this way, we find the group of 4 with the slightly lighter or heavier person. We used the seesaw firts time.

Let’s divide 4 people into 2 groups. Then, Let’s take 2 people on the seesaw and find the light or heavy one. In this way, we will find the person we are looking for in a maximum of 2 attempts.
