Eating, Laughing, Thinking, and YawningMath brain teasers require computations to solve.
Twice the number of people eating equals half of the people who are laughing; if twenty people are thinking, and all of the people thinking are also all of the people laughing... and a quarter of the people laughing are also yawning, then how many people are yawning? How many people are eating?
HintIt is a low level of math, nothing too hard. It just takes some thinking.
E= 0.25 x 20
Y= 0.25 x 20
There are five people eating and five people yawning.
