- Calculating the First Discount:

- The laptop is initially discounted by 20%.

- This means you pay 80% of the original price.

- Calculating the Second Discount:

- The reduced price is again discounted by 20%.

- This means you pay 80% of the reduced price (which was already 80% of the original).

- Final Price Calculation:

- You pay 80% of 80% of the original price.

- This equates to 0.8 * 0.8 = 0.64 (64% of the original price).

- Equivalent Total Discount:

- If you’re paying only 64%, the total discount is 100% - 64% = 36%.

- Conclusion:

- Option 1: 20% is incorrect.

- Option 2: 26% is incorrect.

- Option 3: 30% is incorrect.

- Option 4: 36% is correct.
