Question
The cost of packaging of the oranges is 25% the cost of
fresh oranges themselves. The cost of oranges increased by 30% but the cost of packaging decreased by 45%, then the percentage change of the cost of packed oranges, if the cost of packed oranges is equal to the sum of the cost of fresh oranges and cost of packagingSolution
Let initial Cost of fresh, oranges = 100
packaging cost = 25, Initial total cost = 100 + 25 = 125
After increasing in cost of fresh oranges 30%,
Cost of fresh oranges = 130
And cost of packing go down by 45% so,
Cost of packing = 11.25
Total cost = 130 + 11.25 = 141.25
Increased cost = 141.25 – 125 = 16.25
% increased = (16.25 x 100) /125 = 13%
