B Correct answer
Explanation

Printed price = 25000. After 10% and 20% discounts, cost = 25000 * 0.9 * 0.8 = 18000. Repair cost = 10% of 18000 = 1800. Total cost = 19800. Sale price at 15% profit = 19800 * 1.15 = 22770.

AI explanation

Using the equivalent discount formula, the overall discount is 10 plus 20 minus (10 times 20) divided by 100, resulting in 28 percent. The cost price becomes 25000 times (100 minus 28) divided by 100, which is Rs. 18000, and adding the 10 percent repair cost of Rs. 1800 makes the total cost Rs. 19800. Selling at a 15 percent profit gives a final sale price of 19800 times 115 divided by 100, equalling Rs. 22770.
