Question

In a group of 140 people, 14 like tea, 104 like milk, and each person likes at least one of the two drinks.

How many people like both tea and milk?
A. 10
B. 14
C. 20
D. 25

Answer 1

To determine how many people like both tea and milk, subtract the number of people who like only tea from the total number who like tea. Subtract the number of people who like only milk from the total number who like milk. The answer is 0.

Step-by-step explanation:

To determine how many people like both tea and milk, we can subtract the number of people who like only tea from the total number of people who like tea. Similarly, we can subtract the number of people who like only milk from the total number of people who like milk. Let's calculate:

Number of people who like both tea and milk = Number of people who like tea - Number of people who like only tea

= 14 - (140 - 104) = 14 - 36 = -22

Since the total number of people who like both tea and milk cannot be negative, the correct answer is 0. Therefore, there are no people who like both tea and milk. So, option A, 10, is incorrect and the correct answer is D. 25.
