A shopkeeper sold an item for Rs. 1,800 at a discount of 10% and gained Rs. 200. Had he not given the discount, his gain would be
Selling price = Rs. 1800
Profit = Rs. 200
=> Cost price = $$1800-200=Rs.$$ $$1600$$
Discount % = 10%
=> Marked price = $$\frac{1800}{(100-10)}\times100$$
= $$20\times100=Rs.$$ $$2,000$$
If no discount is given, => Selling price = Rs. $$2000$$
$$\therefore$$ Profit = $$2000-1600=Rs.$$ $$400$$
=> Ans - (B)
