Question

If a commodity is sold with successive discount of 15% and 20% , what Will be the equivalent discount?​

Answer 1

Answer: 32%

Step-by-step explanation:

Let the price of commodity is 100

First discount is 15%, so now the price of commodity is 85.

Second discount is 20% on 85, so now the price is 68.

Now the resultant price is 68. Which can be obtained by giving a 32% single discount on 100

Answer 2

Answer:

Let,

C.P. be ₹ 100.

∴ 1st S.P. = ₹ 85

Again,

∴ 2nd S.P. = ₹ ( 85 × 80/100 )

                 = ₹ 68

∴ Discount = ₹ ( 100 - 68 )

                  = ₹ 32

∴ Equivalent Discount = 32 %               Ans.
