To Find Cost Price when Sale Price and Markup Rate % are Known (WP No.7 Markup)

Nadeem sold a bicycle for Rs.4,500 with markup of 25%. Find the cost price of bicycle.

Given:

Sale price (S.P) = Rs.4,500

Markup Rate = 25% (Markup can also be called a Profit and it implies on Cost Price (C.P))

To Find:

Cost price (C.P) = Rs. ? 

Solution:

Let Cost price (C.P) = X

Markup = 25% of Cost price (C.P) = `{\frac{25}{100}}` X

Markup  = Sale price - Cost price

Cost price = Sale price - Markup 

By putting Values 

X= Rs.4,500 - `{\frac{25}{100}}` X

X + `{\frac{25}{100}}` X = Rs.4,500

`{\frac{125}{100}}` X = Rs.4,500

X = `{\frac{100}{125}}` x Rs.4,500

X = Rs.3,600

Thus the Cost Price (C.P) of Bicycle is Rs.3,600
