Question

The marked price of a shirt is Rs.800. Find the selling price, if he allows successive discounts of 15%, 10% and 8%.

Answer 1

Given, M.P. of the shirt =  Rs.100
First discount = 15%
`"S.P."_1/"M.P." = 1 - "discount"/(100)`

⇒ `"S.P."_1/(800) = 1 - (15)/(100)`

⇒ `"S.P."_1 = (85)/(100) xx "Rs."800`
= Rs.680

Second discount = 10%
`"S.P."_2/"S.P"_1 = 1 - "discount"/(100)`

⇒ `"S.P."_2/(680) = 1 - (10)/(100)`

⇒ `"S.P."_2 = (90)/(100) xx "Rs."680` 
= Rs.612

Third discount = 8%
`"S.P."_3/"S.P"_2 = 1 - "discount"/(100)`

⇒ `"S.P."_3/(612) = 1 - (8)/(100)`

⇒ `"S.P."_3 = (92)/(100) xx "Rs."612` 
= Rs.563.04
∴ Selling Price of the shirt = Rs.563.04.
