Answer:
What is the effective discount (in %) on two successive discounts of 20% and 10%?
Let the amount on which two successive discounts applicable be ₹100
After first successive discount of 20% it's price will be
20/100 × 100 = ₹20
Price after 20% discount = 100 - 20 = ₹80
After 2nd successive discount of 10% it's price
10/100 × 80
= 80/10
= ₹8
Price after 2nd successive discount
= ₹80 - 8
= ₹72
Total discount = 100 - 72 = 28
As the amount of ₹28 has been based on ₹100 as such the percentage dis puny after two successive discount of 20% and 10% it will be 28%
Answer the effective discount (in %) on two successive discounts of 20% and 10% will be 28%
