A radio is sold at a profit of 20%. Had it been sold for Rs. 60 more the profit would have been 30%. The cost price of the radio is

Suppose that C.P. of radio = Rs. y
According to the question,

⇒		130y	-	120y	= 60
		100		100

⇒	10x	= 60
	100

⇒ y = 60 × 10 = Rs. 600
We can find required answer with the help of given formula :
Here, a = 20%, R = Rs 60, b = 30%

C.P. =	R	× 100
	(b - a)

C.P. =	60	× 100 = Rs. 600
	(30 - 20)
