Successive Discount : The formula for total discount in case of successive-discounts : 
If the first discount is x% and 2nd discount is y% then ,
Total discount = ( x + y - xy / 100 ) %Example : 

1) The successive-discount of 10% and 20% are given on the purchase of a bag . If the price of the bag is $ 2250, find the selling price.

Solution: 
As the successive discount is 10% and 20% 

Total discount = ( x + y - xy / 100 ) % 

x = 10% and y = 20% 

Total discount = [ 10 + 20 – ( 10 x 20) / 100] % 

= ( 30 – 200 /100 ) % 

Total discount = 28% 

Discount = 28% of 2250 

Discount = ( 28 / 100 ) x 2250 

Discount = $630 

S.P = M.P – Discount 

= 2250 – 630

Selling price = $ 1620

Total discount = [ 10 + 20 – ( 10 x 20) / 100] %

Total discount = 28% 

Discount = 28% of 2250 

Discount = ( 28 / 100 ) x 2250 

Discount = $630 

S.P = M.P – Discount 

= 2250 – 630

Selling price = $ 1620
