In a town, 80% of the population are adults, of which the population of adult men and women is in the ratio of 2 : 3. If the number of adult men is 1.2 lakh, what is the total population of the town?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 3.75 lakh.
Calculations:
Let the total population = 100x
The total adult population = 80x
The ratio of adult men and women = 2 : 3
The adult men population = 80x/(3 + 2) × 2 = 32x
Given, 32x = 1,20,000
⇒ x = 3750
Thus, the total population = 100x = 100 × 3750 = 3,75,000 or 3.75 lakh
