Question

There are 15 clowns in a circus. Each clown has to act either happy or sad. Twelve of the clowns have red noses. Each of the seven happy clowns has a red nose. Five of the sad clowns have red noses. How many clowns have to act sad and do not have a red nose?

Answer 1

Answer:

3

Step-by-step explanation:

• Each of the seven happy clowns has a red nose.

This means there are (15-7) 8 sad clowns.

• Five of the sad clowns have red noses.

This means out of 8 sad clowns, 5 have red noses. So the clowns that have to act sad and have red noses are (8-5) 3.
