Question

$40\%$ of the population of a town are men and $35\%$ are women. If the number of children is $20000$, find the number of men.

Answer 1

Assume total number of members in a town=x

number of men=0.4x

number of women=0.35x

So,

number of children=total-(number of men+number of women)

=x-(0.4x+0.35x)

=0.25x

As,

number of children=20000

So,

0.25x=20000

x=80,000

Number of men=0.4(80,000)

=32,000

So, 32,000 mens are present in town
