Question

(i) A number is increased from 125 to 150; find the percentage increase.
(ii) A number is decreased from 125 to 100; find the percentage decrease.

Answer 1

(i) Original vlaue = 125. New value = 150
Increase = (150-125) = 25
Increase % = $\frac{25}{125}\times$ 100 = 20%
(ii) Original number = 125, New value = 100,
Decrease = (125-100)= 25
Decrease % = $\frac{25}{125}\times$ 100 = 20%
