We can solve this question by using equivalent ratios
We'll use the ratio: preferred Brand X/preferred Brand Y
Given: 120 preferred Brand X
Let y = the number of people who preferred Brand Y
We get: 120/y = 3/1
Cross multiply to get: 3y = 120
Solve: y = 40
So, 120 people preferred Brand X, and 40 people preferred Brand Y
TOTAL number of people = 120 + 40 = 160
Answer: B
