B Correct answer
Explanation

Let MP be x. After 20% discount, SP = 0.8x. Loss rate = half of discount rate = 10%. So SP = 0.9 × CP = 0.9 × 42000 = Rs. 37800. Therefore 0.8x = 37800, giving x = Rs. 47250. Option A (42000) equals CP, Option C (37800) is the SP after discount, and Option D (40500) doesn't satisfy the conditions.
