A Correct answer
Explanation

Let marked price be M. After 18% discount, selling price = 0.82M. Profit is 23% of cost price, and actual profit = Rs. 18.40. So 0.23 × CP = 18.40, CP = 80. Selling price = CP + profit = 80 + 18.40 = 98.40. But SP also equals 0.82M, so M = 98.40/0.82 = 120. Therefore marked price = Rs. 120.
