Question

Decrease 240kg by 12½%​

Answer 1

210 kg.

Explanation:

We have to decrease 240 kg by
`12(1)/(2)`%.

First we have to find what is
`12(1)/(2)`% of 240 kg.

Now,
`12(1)/(2)`% is equivalent to
`(25)/(2) \%`.

So,
`(25)/(2) \%` of 240 kg is equal to
`(240 * 25)/(2 * 100) = 30`.

Therefore, decreasing 30 kg from 240 kg will be equal to (240 - 30) kg = 210 kg. (Answer)
