In order to find the quantity increase of the given numbers; 12 and 15, find first their common difference.

The common difference can be found by subtracting the smaller number to the bigger number.

=15 - 12

= 3

Now in order to find the percentage increase, divide the common difference by the smaller number.

=3 / 12

= 0.25

Multiply 0.25 by 100 to get the percentage.

= (0.25) (100)

= 25%

The percent increase is 25%
