A Correct answer
Explanation

Marked price = 1,100. Discount = 10%, so Selling Price = 1,100 * 0.9 = 990. Gain = 10%, so Cost Price * 1.1 = 990. Cost Price = 990 / 1.1 = 900.

AI explanation

The selling price of the sewing machine is the marked price minus the 10 percent discount, which is 1100 minus 110, equaling 990. Using the formula cost price equals selling price divided by (1 plus profit percentage), the cost price is 990 divided by 1.10. Calculating this gives a cost price of Rs 900.
