Question 64

In a town, 80% of the population are adults, of which the population of men and women is in the ratio 2 : 3. If the number of adult men is 1.2 lakh, what is the total population of the town?

Solution

population of men and women is in the ratio 2 : 3. If the number of adult men is 1.2 lakh.

number of adult men = 1.2 lakh = 120000

population of adults = $$\frac{120000}{2}\times\ \left(2+3\right)$$

= $$60000\times\ 5$$

= 300000

In a town, 80% of the population are adults.

total population of the town = $$\frac{300000}{80}\times\ 100$$

= $$3750\times\ 100$$

= 375000

= 3.75 lakh
