Question

a singel dicount equivalent to two successive discount of 20% and 15% will be​

Answer 1

Answer:

Let the price of item on which the two successive discount of 15% and 20% applicable be 100

First discount of 15% on ₹100 = ₹15

Price after 15% Discount = ₹85

Successive discount of 20% will be applicable on price after 1st discount

20% of ₹85

20/100 × 85

= 85/5

= ₹17

Price of the item after second discount

= ₹85 - ₹17

= ₹68

Two successive discounts total = ₹15 + ₹ 17 = ₹32

As the price of the item before calculation was taken as ₹100 therefore the sum of successive discounts of 15% and 20% or single discount is equal to 32%

Answer : Two successive discounts of 15% and 20% are equal to single discount of 32%
