The population of a town is 35 × 103. If the number of males increase by 6% and the number of females by 4% the population would become 36760 after a year. Find the number of males in the town:
Explanation:
Given population, p = 35000
Let male population be m
Then, female population would be (35,000 – m)
From the problem,
1.06m + 1.04(35000 – m) = 36760
1.06m + 36400 – 1.04 m = 36760
⇒ 0.02m = 360
⇒ m = 360/0.02 = 18,000
Hence, option (d).
