Charging 30 % above its production cost a radio maker puts

Charging 30 % above its production cost a radio maker puts a label of ₹ 286 on a radio as its price. But at the time of selling it, he allows 10 % discount on the labelled price. What will his gain be ?

Let Production cost of radio= ₹ p

∴	p × 130	= 286
	100

⇒ p =	286 × 100	= ₹ 220
	130

∴ Selling price = 90% of 286

∴ Selling price =	286 × 90	= ₹ 257.40
	100

Required Profit = ₹ (257.40 – 220) = ₹ 37.40
