Question

The sum of the ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child? Select one:

a. 8 years

b. 4 years

c. 10 years

d. None

Answer 1

None because the youngest children age is 12

Answer 2

Answer:

Let the ages of children be x, (x + 3), (x + 6), (x + 9), (x + 12) years.

According to Question now,

➳ x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

➳ 5x + 30 = 50

➳ 5x = 50 - 30

➳ x = 20/5

➳ x = 4 years

Therefore,the age of youngest child is 4 years.
