Answer 1

Let the marked price of an article be Rs. 100

Then first discount on it =Rs. 20

Price after discount =Rs. (100-20)=Rs. 80

Second discount on it =10% of Rs. 80

Rs.(80×

100

10

)=Rs.8

Price after second discount =Rs. (80-8)=Rs. 72

Net selling price =Rs. 72

Single discount equivalent to given successive discounts =(100-72)%=28%
