B Correct answer
Explanation

15 * SP = 18 * CP. SP/CP = 18/15 = 6/5. Profit = (6-5)/5 = 1/5 = 20%.

AI explanation

Let the selling price of one article be S and the cost price be C. The equation is 15S = 18C, which simplifies to S/C = 18/15 or 6/5. The profit percentage formula is ((S - C) / C) * 100, which becomes ((6 - 5) / 5) * 100. The result is a 20% profit.
