Answer: (2) 20%

Explanation:-
Let the cost price of an article be Rs.1
Then, the cost price of 15 articles = Rs. 15 

Selling price of 15 article = Rs. 18
Profit = 18 – 15
 = Rs. 3

So, the percentage of profit = 3 x 100/15
 = 20%

Then, gain percent is 20%. 

Hence, the correct is option (2) 20%.
