Question
An item was sold at a 22% loss. If the selling price had
been increased by Rs. 1,850, there would have been a 15% profit instead. Determine the original cost price of the item.Solution
Let cost price of the article = Rs. ‘100x’ ATQ, 1.15 × 100x – 0.78 × 100x = 1850 Or, 115x – 78x = 1850 Or, 37x = 1850 Or, x = (1850/37) = 50 So, cost price of the article = 100x = 100 × 50 = Rs. 5,000
