Solution:

As per the problem

A person is born every 5 seconds and a person dies every 12 seconds.

Here the LCD of 5 and 12 is 60.

The number of person born in 60 seconds=\frac{60}{5}=12\\

The Number of person died in 12 seconds=\frac{60}{12}=5

Hence Population increase in 60 seconds is=12-5=7\\

Hence time required to increase the population by one =\frac{60}{7} \ \ seconds\\
