The cost price of an item is ₹400. After giving a discount of 15%, the profit earned is 25%. What was the marked price?
Correct Answer:
A. ₹588.24
Explanation:
Step 1: Profit = 25% of ₹400 = 0.25 × 400 = ₹100.
Step 2: Selling Price = Cost Price + Profit = 400 + 100 = ₹500.
Step 3: Let Marked Price = M.
After 15% discount: M × (1 - 0.15) = 500, so M × 0.85 = 500, M = 500/0.85 = ₹588.24 (approximately).
Therefore, option A is correct.
