Successive discounts of 20 % and 10 % equivalent to a single discount of how many percent?

Solution:
Your problem `->` Successive discounts of 20 % and 10 % equivalent to a single discount of how many percent?


Let marked price = Rs. `100` S.P.

After first discount = `80` % of `100` S.P.

After second discount = `90` % of `80` % of `100` = Rs. `72` .

This is equivalent to a single discount of `( 100 - 72 ) % = 28 %`.
