Question

Find a single discount equivalent to the following successive discounts:
(i) 15 %, 25 %,
(ii) 10 %, 20 % and 5 %
5% 10% 15%​

Answer 1

Step-by-step explanation:

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%

Answer 2

1) final payment = 85%*75% = 63.75%
Equivalent discount = 100-63.75= 36.25%
2) payment = 90%*80%*85%= 61.2%
Equivalent dis 100-61.2 = 38.8%
3) payment = 95%*90%*85% = 72.675%
Equivalent dis = 27.325%
