AI explanation

To find Y's exact profit from a total of Rs. 40000, you must determine Y's proportionate share of the total investment. Statement A gives the full ratio of 3 : 6 : 7, but it lacks the actual monetary values to validate the specific conditions of B and C, whereas statement B provides Y's actual investment of Rs. 30000 and the ratio needed to find the other amounts, and statement C establishes the relative profit distribution. Statements B and C together supply both the exact numerical investments and the proportional profit differences needed to calculate Y's monetary share, making them the necessary combination.
