Question

A group of young adults were surveyed about their favorite pizza topping. The toppings of pepperoni and sausage were in the ratio of 5:7. If there were 120 people surveyed, how many said pepperoni was their favorite?

Answer 1

Given:

A group of young adults was surveyed about their favorite pizza topping.

The toppings of pepperoni and sausage were in the ratio of 5:7

So, using the ratio and proportions:

pepperoni : sausage : total

5 : 7 : 12

x : y : 120

The number of people who said pepperoni was their favorite = x

`x=5\cdot(120)/(12)=5\cdot10=50`

So, the answer will be 50 people said pepperoni was their favorite
