The total population of a village is 5000. The number of males and females increases by 10% and 15% respectively and consequently the population of the village becomes 5600. What was the number of males in the village ?
Let the number of males be `x`. Then, number of females = (5000 - `x`)
`:.` 10% of `x` + 15% of (5000 - `x` = 5600 - 5000
`hArr 10/100 x + 15/100 (5000 - x)` = 600 `hArr 10x + 75000 - 15x = 60000`
`hArr 5x = 15000 hArr x = 3000`
