C Correct answer
Explanation

Let profit amounts be equal: 10% of CP_A = 15% of CP_B. This means CP_A/CP_B = 15/10 = 3/2. Option C (3000, 2000) satisfies this ratio (3:2). Check: 10% of 3000 = 300, 15% of 2000 = 300 - both profits are equal. Option A gives ratio 2:3, B gives 5:2, D gives 3:5 - none match the required 3:2.
