Solution:

Given:

10 is 25%

To find:

The number of 25% is 10.

Step-by-step explanation:

Let x be the number of 25% is 10.


x * 25\% = 10 \\ x * (25)/(100) = 10

Multiply both sides by 100.


x * (25)/(100) * 100 = 10 * 100 \\


x * 25 = 1000

Divide both sides by 25.


x * (25)/(25) = (1000)/(25)


* = 40

Final answer:

The required number is 40.
