C Correct answer
Explanation

Let MP be the marked price. After 15% discount, selling price = 0.85 × MP. For 20% profit on cost of Rs. 153, selling price should be 1.2 × 153 = Rs. 183.60. Therefore 0.85 × MP = 183.60, giving MP = 183.60/0.85 = Rs. 216. The shopkeeper marks Rs. 216, offers 15% discount (Rs. 32.40 off), and sells at Rs. 183.60 for a 20% profit.
