Answer 1

Let the two numbers are 25x and y
According to the question,
25x + y = 28x
So, y = 3x
or, y = 25x * 3/25
so, the percentage is
= 3*100/25
= 12

Answer 2

Let the number be x andy.

Given, x + y = 28/25 * x

                y = 28/25 * x - x

                   = 3/25 * x

                y/x = (3/25 * 100)%

                      = 12%.
