# Finding the Increase or Decrease Percent

Example

The price of a bike was Rs. 45000 last year. It has increased 20% this year. What is the price now?

Solution

The price of a bike = Rs. 45,000
Increased percentage = 20

New price = Old price + Increase
= Rs. 45000 + Rs. 9000
= Rs 54,000

In order to increase its sale, the price of a bike was decreased by 5%. Then let us find the price of bike.

Price of bike = Rs. 45000
Reduction    = 5% of 45000

New price = old price - Reduction
= Rs. 45000 - Rs. 2250
= Rs. 42750

Finding Discounts :-
Discount is a reduction given on the marked price (MP) of the article.

Discount = Marked Price- Sale price

Example

A shirt is marked at Rs. 950 is sold for Rs. 700. What is the discount and discount %.

Solution

Discount = Marked price - Sale price
= Rs. 950 - Rs. 700 = Rs. 250

On marked price of Rs. 950 the discount is Rs. 250

Example

The list price of a saree is Rs. 350. A discount of 20% is announced on sales. What is the amount of discount on it and sale price.

Solution

Marked price is same as the list price. 20% discount means that on Rs. 100 (MP), the discount is Rs. 20.

On Rs. 350, discount

The sale price = (Rs. 350 - Rs. 70) = Rs. 280
