Question
The total population of a town is 18000. The male
population increases by 70 percent and female population increases by 40 percent. If the total population becomes 27000, then what were the initial number of females in the town?Solution
ATQ, Let the initial numbers of females be f Then, number of males initially = 18000 - f According to the question, Increased population = 1.4f + 1.7(18000 - f) = 27000 ⇒ 30600 - 0.3f = 27000 ⇒ f = 12000 ∴ Initial number of females = 12000
