Question

The sum of the ages of five children born at interval of 3 years each is 50 years.What is the age of the youngest child?\

Answer 1

Answer:

Let the youngest child's age isx

then X+(x+3) +(x +6) + (x+9)+(x +12)

= 5x+30 = 50

5x=50-30=20

x = 20/5=4

the age of the youngest=4 yrs

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.
