Cost is R60 is on sale for R36 What's a discount percentage?

To calculate the discount percentage, we can use the formula:

Discount Percentage = (Original Price - Sale Price) / Original Price * 100

In this case:
Original Price = R60
Sale Price = R36

Discount Percentage = (60 - 36) / 60 * 100
Discount Percentage = 24 / 60 * 100
Discount Percentage = 0.4 * 100
Discount Percentage = 40%

Therefore, the discount percentage is 40%.
