Discount is aShopkeeper devise several schemes to attract customers. One way to attract customer is giving rebate or reduction in price.

The price

Reduction is generally given as a certain percent (%) of the marked price. Customer pays the difference between the marked price and the rebate.

Reduction = M.P - S.P |

Reduction % = (Discount / M.P) x 100 |

S.P = M.P - Discount |

1) Marked price of a book is $40. It is sold at a rebate of 20%. Find the discount allowed on the book and its selling price.

2) An item marked at $840 is sold for $ 714. What is the rebate and reduction %?

Reduction = Marked price - selling price

= 840 - 714

Reduction = $126

As Reduction is on marked price,

Reduction % = (Discount/M.P) x 100

= (126/840) x 100

= 12,600/840

Hence, Reduction % = 15

3) Find the selling price of :

Original price of a microphone: $49.99

Reduction: 5%

Tax: 5%

Original price of a microphone: $49.99

Reduction: 5%

Tax: 5%

5/100 = Reduction/49.99

Cross multiply

100 x Reduction = 49.99 x 5

100 x Reduction = 249.95

So, Reduction = 249.95/100

Reduction = $2.4995

S.P = Original price - Reduction

= 49.99 - 2.4995

= $47.4905

Hence, selling price is $47.49

4) The marked price on a book is $450. The shopkeeper gives 20% Reduction on it in a book exhibition. What is the selling price ?

Solution :

Marked price = M.P. = $450

Reduction of 20 % of 450

Reduction = ( 20 / 100 ) x 450

= 9000/ 100

Reduction = $90

S.P = M.P – Reduction

= 450 – 90

Selling price = $360
