C Correct answer
Explanation

Let A's income be x and B's income be (33000-x). A saves 40% (spends 60%) and B saves 25% (spends 75%). Their savings ratio is 4:3, so 0.4x/0.25(33000-x) = 4/3. Cross-multiplying: 1.2x = 0.333(33000-x). Solving: x = Rs. 15,000. Verification: A saves Rs. 6,000, B saves Rs. 4,500, ratio = 4:3 ✓
