Question

In a town, $40\%$ are male and $30\%$ are female and rest are children. Find the number of children if the total population is $2$ lakh.

Answer 1

Percentage of male in the town $=40\%$

Percentage of female in the town $=30\%$

Therefore,

Percentage of children in the town $=(100-(40+30))\%=30\%$

Total population of the town $=200000$

Therefore,

Total no. of children in the town $=\frac{30}{100}\times 200000=60000$

Hence the number of children in the town is $60000$.
