Question
A product is sold at 15% profit. If its cost price had
been 25% lower, and it was sold at a 30% loss, the seller would have made Rs. 280 less. What was the original cost price of the product?Solution
ATQ,
Let the original cost price be Rs. x Original selling price = 1.15x New cost price = 0.75x (25% less) New selling price = 0.7 × 0.75x = 0.525x (30% loss on new cost price) Difference in earnings = 1.15x – 0.525x = Rs. 280 ⇒ 0.625x = 280 ⇒ x = 280 / 0.625 = Rs. 448
