Question

The product of the ages of three children is 1872. The age of the middle child is the average of the ages of the other two children. What is the sum of their ages

Answer 1

The total age of the three children are = 37years

Calculation of the total age of children

The product of the ages of three children is = 1872.

Let take child 1 = x

child 2 = x

child. 3 = x

Therefore, the age of three children = x³= 1872

Therefore;

$x = \sqrt[3]{1872}$

X = 12.32448

The age of the middle child = 12.32448 + 12.32448

= 24.64896/2

= 12.32448

Therefore the sum of their ages = 12.32448 + 12.32448 + 12.32448 = 37years.
