Ali bought 5 apples at a cost of Rs.5 each. What will be the percentage of discount if Sheeraz buys 9 apples at a cost of Rs.4 each?

Explanation

To find the percentage of discount:

Original price per apple = Rs. 5

Sheeraz's price per apple = Rs. 4

Discount per apple = Original price - Sheeraz's price

= Rs. 5 - Rs. 4

= Rs. 1

Percentage of discount = (Discount / Original price) × 100

= (1 / 5) × 100

= 20%
