Question

Find the single discount equivalent to the series of discount 20% 10% and 5%

Answer 1

Solution:

Let us consider that the marked price of a product is 100.

Applying 20% discount on it, we get,

(20 / 100) * 100 = 20

New price = 100 - 20 = 80

Applying 10% discount on it, we get,

(10 / 100) * 80 = 8

Now the new price is = 80 - 8 = 72

Applying 5% discount on it, we get,

(5 / 100) * 72 = 3.6

Now the new price = 72 - 3.6 = 68.4 

Applying a single discount of 31.6% on 100, we get,

(31.6 / 100) * 100 = 31.6

New price = 100 - 31.6 = 68.4

Hence the single discount is 31.6%.
