Home » Aptitude » Discount » Question

A shopkeeper buys an article for ₹ 180. He wishes to gain 20% after allowing a discount of 10% on the marked price to the customer. The marked price will be

1. ₹ 210
2. ₹ 240
3. ₹ 270
4. ₹ 300

Correct Option: B

Given in question , CP of article = ₹ 180

After 20% gain , SP = 180 ×	120	= ₹ 216
	100

discount = 10%
∴ ( 100 - 10 )% = 216
⇒ 90% = 216

100% =	216	× 100 = ₹ 240
	90

Hence , The marked price is ₹ 240 .
