Question
A shopkeeper bought article βAβ for Rs. βxβ and
marked it 20% above its cost price and sold it for Rs. 3000. Marked price of article βBβ is Rs. 700 more than that of article βAβ while selling price of article βBβ is Rs. 200 more than that of βAβ. Find the cost price of article βAβ if article βBβ is sold at a discount of 20%.Solution
Selling price of article βBβ = 200 + 3000 = Rs. 3200 Marked price of article βBβ = 3200/0.80 = Rs. 4000 Marked price of article βAβ = 4000 β 700 = Rs. 3300 Cost price of article βAβ = 3300/1.2 = Rs. 2750
