Question

A certain Organization adopted 18% of the 400 schools in a district. How many schools did it adopt?

Answer 1

Here, 18% means 18 schools adopted out of a total of 100.
The total number of schools is 400.
Suppose the number of schools adopted is A.

`"A"/400 = 18/100`

`"A"/400 xx 400 = 18/100 xx 400`

∴ A = 72.

∴ The number of schools adopted is 72.
