### Example Questions on Percentage Decrease

1. Price of Sugar Decreases from $9 to $7.5 per Kg? What is the Percentage Decrease in the Price of Sugar?

Solution:

Original Price of the Sugar = $9

New Price of the Sugar = $7.5

Decreased Price of Sugar = $9- $7.5

= $1.5

2. A shopkeeper sells a pair of pens for Rs. 30 initially. He then reduced the price of the pair of pens to Rs. 24. Calculate the Percentage Decrease in the cost of pens?

Solution:

Original Cost of Pair of Pens = Rs. 30

New Cost of Pair of Pens = Rs. 24

Decreased Value = Original Cost – New Cost

= Rs. 30 – Rs. 24

= Rs. 6

Percentage Decrease = (Decreased Value/Original Value)*100

= (6/30)*100

= 20%

Therefore, Percentage Decrease in the cost of pens is 20%.
