Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ₹7,160.
Sum of the income of A and B = 2 × 3590 = ₹7180
Sum of the income of B and C = 2 × 4250 = ₹8500
Sum of the income of C and A = 2 × 6500 = ₹13000
2(A + B + C) = 7180 + 8500 + 13000 = ₹28680
A + B + C = ₹14340
Income of C = 14340 - 7180 = ₹7160
