If a product is sold at Rs. 90 with a loss of 10%, what was the cost price?

Question

Accepted Answer

In this problem, we work backwards from the selling price and loss percentage to find the cost price. Given: Selling Price = Rs. 90, Loss = 10%. When there's a 10% loss, the selling price is 90% of the cost price. Using the equation: 0.9 × CP = 90, we get CP = 90 / 0.9 = Rs. 100. This can be verified: 10% loss on Rs. 100 = Rs. 10, so selling price = 100 - 10 = Rs. 90. This type of reverse calculation is common in SSC exams and tests understanding of loss percentage concepts.
