If an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.
Given that, an original quantity is 12, and the new quantity is 15.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here,
Percentage increase = (New quantity - Original quantity)/Original quantity ×100
= (15-12)/12 ×100
= 3/12 ×100
= 0.25×100
= 25%
Therefore, if an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.
