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%
