Question

A radio station is giving away a $100 bill to every 30th caller and movie tickets to every 10th caller. If there are 120 callers, how many callers will get both the $100 and the movie tickets?

Answer 1

4 callers

Explanation:

Because 10 is a factor of 30, we don't have to worry about it. Every 30th caller will get both rewards. 120/30=4 so the answer is 4.
