Your welcome

Answer 2

Answer: 200%

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%
