Question

1 25% of what number is 13?

Answer 1

Explanation:

Let 25% of x be 13

`\therefore \: (25)/(100) * x = 13 \\ \\ \therefore \: (1)/(4) * x = 13 \\ \\ \therefore \: x = 13 * 4 \\ \\ \therefore \: x = 52`

Hence, 25% of 52 is 13.

Answer 2

25% is 25/100=1/4. If 1/4 of x is 13, then 13x4 would equal x. X=52
