Number of consumers in the age group 26-40 who did not prefer drink B is
Solution
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 the age group 26 - 40, Males: 840 - 480 = 360 did not prefer B, Females: 540 - 360 = 180 did not prefer B, in total 360 + 180 = 540 is the required answer.
