Find a single discount equivalent to the discount series of 5 percent, 15 percent, and 25 Percent?​

Answer»

Answer:

CONSIDER 100/-

A DISCOUNT of 10% would save you 10/-, leaving you with 90/-

Another discount, of 15% this time would be on 90/-

90 x 15/100 = 13.5. Hence money LEFT is (90-13.5) = 76.5

Now, a discount of 20% on 76.5/- = 76.5 x 20/100 = 15.3/-

Hence total discount = sum of total money saved(in this scenario when you work with base 100/-)

= 15.3 + 13.5 + 10

= 38.8

= 38.8% of the ORIGINAL price.

Hence the discount is 38.8%
