Answer 1

SP=(1-d/100) (1-d/100)*MP
=(1-10/100) (1-20/100)*1000
=90/100*80/100*1000
=9*80
=720

Answer 2

Given,

First discount is of 10%

Second discount is of 20%

The marked price of the frying pan is rupees 1000

To find,

The final price of the frying pan after two successive discounts.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Price after the first discount = 1000 - ( 1000 × 10/100) = 1000 - 100 = Rs. 900

Price after the second discount = 900- (900×20/100) = 900-180 = Rs. 720

[This will be the final price after the two successive discounts of 10% and 20%]

Hence, the final price will be Rs. 720
