A shopkeeper allows a discount of 10% on the marked price

A shopkeeper allows a discount of 10% on the marked price of an item but charges a sales tax of 8% on the discounted price. If the customer pays ₹ 3,402 as the price including the sales tax, then the marked price is

Let Marked price of article = ₹ p

∴ S.P. of article = ₹		p ×	90	×	108
			100		100

∴ p ×	90	×	108	= 3402
	9		9

⇒ p =	3402 × 100 × 100
	90 × 108

Hence Marked price of article = ₹ 3500
