Answer: 200%
Step-by-step explanation:
A radio when sold at a certain price gives a gain of 20 %.
Selling Price = 3 × Cost Price
TO FIND :- Gain percent
Gain % = gain / cp x 100
20 = (gain x 100) / cp
Gain/cp = 20/100 = 1/5
Gain = SP - CP
= 3CP - CP
Gain = 2CP
Gain% = gain / cp x 100
= 2cp / cp x 100
= 2 x 100 = 200%
