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.

=> 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 41-60 category: The number of consumers who preferred either of the two drinks = 420 + 360 = 780.

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.

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:

Total consumers above 40 years old = 1200 + 960 = 2160; out of these, 780 + 600 = 1380 preferred none of the drinks.

=> Required %age = 1380/2160 * 100 = 63.88 = 69%

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.

Total consumers above 40 years old = 1200 + 960 = 2160; out of these, 780 + 600 = 1380 preferred none of the drinks.

=> Total number of consumers who did not prefer any drink is 270 + 90 + 780 + 480 + 240 + 600 = 2460
