Explanation

Percentage below 40 years = 14.00 + 29.75 + 26.25 = 70%. 70% of Total = 10.5 lakhs. Total = 10.5 / 0.7 = 15 lakhs.

AI explanation

First, sum the percentages of the population below 40 years old: 14.00 + 29.75 + 26.25 = 70.00%. This 70% of the total population corresponds to 10.5 lakhs. To find the total population, divide the number of persons by their percentage representation, so 10.5 / 0.70 equals 15 lakhs.
