Question
A shopkeeper marked an article Rs. 650 above its cost
price and sold it after giving a discount of 15% and earned a profit of 35%. Find the cost price of the articleSolution
Let cost price of the article is Rs. 100x So, 1.35 × 100x = 0.85 × (100x + 650) Or, 135x = 85x + 552.5 Or, 50x = 552.5 Or, x = 11.05 Cost price of the article = 100 × 11.05 = Rs. 1600
