The table given below indicates the number of consumers who preferred one or both drinks. Read the table and answer questions.
Let's tabulate all the information from the given table:
The calculation is as follows:
Consider the male 18 - 25 range:
=> Total consumers = 600
=> Out of them, 240 like A, 180 like B, 90 like both
=> Number of people who like either = 240 + 180 - 90 = 330
=> 600 - 330 = 270 people don't like any of the drinks.
Doing the same calculation for all the categories and tabulating, we get:
In 18-25:
Males: Number of people who only prefer 1 drink = 240 + 180 - 2*90 [subtracting those who like both] = 240
Females: 180 + 120 - 2*60 = 180
=> Required answer = 240 + 180 = 420.
