An article was sold for ₹2,500. Had a discount of 10% been offered, a profit of 12.5% would have been made. What was the cost price?

The correct answer is
₹2,000

Calculating Cost Price with Discount and Profit

This solution finds the Cost Price (CP) using the information about a hypothetical discount and profit scenario. We interpret the initial selling price, ₹2,500, as the Marked Price (MP) for the calculation.

Step 1: Calculate Hypothetical Selling Price

First, find the Selling Price (SP) that would occur if a 10% discount was applied to the Marked Price (MP).

  • Marked Price (MP) = ₹2,500
  • Discount Rate = 10% or $0.10$
  • Using the formula \(SP = MP \times (1 - \text{Discount Rate})\):
  • \(SP = ₹2,500 \times (1 - 0.10)\)
  • \(SP = ₹2,500 \times 0.90\)
  • \(SP = ₹2,250\)

This calculated SP of ₹2,250 is the price at which a 12.5% profit would be made.

Step 2: Calculate Cost Price

Now, use the hypothetical Selling Price and the given profit percentage to calculate the Cost Price (CP).

  • Hypothetical Selling Price (SP) = ₹2,250
  • Profit Rate = 12.5% or $0.125$
  • Using the formula \(SP = CP \times (1 + \text{Profit Rate})\):
  • \(₹2,250 = CP \times (1 + 0.125)\)
  • \(₹2,250 = CP \times 1.125\)
  • Rearranging to solve for CP: \(CP = \frac{₹2,250}{1.125}\)
  • \(CP = ₹2,000\)

The Cost Price of the article is ₹2,000.
