A cafeteria manager needs to know how many apples and bananas to place in a cafeteria vending machine. He conducted a survey, and all students who respended chose either an apple or banana as their preferred fruit. The survey results show that 3/4 of the students who responded picked apples. If 120 students picked apples, how many picked bananas?

3/4 of total = 120
therefore, 1/4 took bananas
the ones taking bananas are 3 times less than those who took apples.
so we get 120/3 = 40 people picking bananas
