D Correct answer
Explanation

Let A's share be x, then B's share is (25230-x). A invests for 13 years (40-27), B for 15 years (40-25). With 5% CI, future values must equal: x(1.05)^13 = (25230-x)(1.05)^15. Simplifying: x = (25230-x)(1.05)^2 = (25230-x)(1.1025). Solving: x = 13230. A receives Rs. 13230.
