Children of a class were asked which of these they liked the most - Tea, Coffee or Milk. Children who like Tea, Coffee and Milk are 1/2, 1/3 and 1/6 respectively of the total children of the class. If 20 children like coffee, how many children like milk? Correct Answer 10

Given:

Total children like coffee = 20

Calculation:

Let the total children in the class = y

From the total children like tea = (1/2)y

Coffee like = (1/3)y

Milk like = (1/6)y

Coffee like = 20 children

According to the question, total number of children like coffee are 20

⇒(1/3)y = 20

⇒ y = 3 × 20 = 60

Hence, total number of children in the class = 60

Children like milk = (1/6) × 60 = 10

∴​ 10 children like milk.
