While selling to the retailer, a company allows 30% discount on the marked price of its products. If the retailer sells those products at marked price, his profit per cent will be ________.
Explanation:
Let the marked price of the product = Rs. 100
Cost price of product for retainler = 70% of 100 = Rs. 70
Retailer sells it for Rs. 100.
∴ Retailer's profit = 100 - 70 = Rs. 30
⇒ Retailer's profit % = 30/70 × 100% = 42(6/7)%
Hence, option (b).
