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

[tex]x=5\cdot\frac{120}{12}=5\cdot10=50[/tex]

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