Question

When a number is decreased by 40% of itself, the result is 24 what is the number?

Answer 1

Answer: The number is 40.

Explanation:

Since we have given that

Let the number be 'x'.

If a number is decreased by 40%.

So, number becomes,

`(100-40)/(100)* x\\\\=(60)/(100)* x\\\\=0.6x`

According to question, the result becomes 24.

So, our equation becomes,

`0.6x=24\\\\x=(24)/(0.6)\\\\x=(240)/(6)\\\\x=40`

Hence, the number is 40.
