Suppose the cost for 100 ounce of candy bar was X.
Which means cost for 1 ounce = X/100

Since the weight was reduced by 20% and priced remained same, now 80 ounce of candy bar costs X. i.e cost of 1 ounce is X/80.

Now % increase is given [(X/80) - (X/100)] / (X/100) = 0.25 = 25%

Some quick calculation.....

Earlier if 100 ounces cost 100$, now 80 ounces cost 100$. So as per the present price 100 ounces will cost 125$. So the percentage increase is 25%
