A shopkeeper marks up an article by 60% on its cost price. He allows a discount of 25% on the marked price. If the selling price of the article is Rs 900, then find the cost price (in Rs).

Explanation

​ Information Given: Markup = 60% on Cost Price Discount = 25% on Marked Price Selling Price (SP) = ₹900 Concept/Formula Used: Marked Price (MP) = CP × (1 + Markup%) Selling Price (SP) = MP × (1 − Discount%) Explanation: Let Cost Price (CP) = x MP = x × 1.6 SP = MP × 0.75 So, SP = x × 1.6 × 0.75 900 = x × 1.2 x = 900 / 1.2 = 750
