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

Answer Posted / hafiz ulla

Let no. of men be x

and no. of women be 5000 - x



Population increased from 5000 to 5600

i.e. 600

men increased % = 10% of x

And women increased % = 15% of (5000 - x)



so, 10% x + 15%(5000 - x) = 600

10/100 + 15/100(5000 - x) =600

10x + 75000 - 15x = 60000

-5x = -15000

x = 3000

So, the no. of males = 3000.
