₹10,000

This question requires calculating the original price before discounts were applied.

Calculating Original Price with Successive Discounts

Let the original price of the product be P.

Two successive discounts are applied: 20% and 10%.

  • After the first discount of 20%, the remaining price is (100% - 20%) = 80% of the original price.
  • After the second discount of 10% on the new price, the final price is (100% - 10%) = 90% of the price after the first discount.

The final price after both discounts is given as ₹7,200.

Step-by-Step Solution

  1. Represent the discounts mathematically. The price after the first discount is \(P \times (1 - 0.20) = P \times 0.80\).
  2. Calculate the price after the second discount. This is applied to the price obtained in the previous step: \((P \times 0.80) \times (1 - 0.10) = P \times 0.80 \times 0.90\).
  3. Set up the equation with the final price: \(P \times 0.80 \times 0.90 = 7200\).
  4. Simplify the discount multiplication: \(P \times 0.72 = 7200\).
  5. Solve for the original price P by dividing the final price by the combined discount factor: \(P = \frac{7200}{0.72}\).
  6. Calculate the final value: \(P = 10000\).

Therefore, the original price of the product was ₹10,000.
