Averages Q.1
- Option : B
- Explanation : Total of A and B = (5,050 × 2) = 10,100 (i)
Similarly, total income of B and C = (6250 × 2) = 12,500 (ii)
And total of A and C = (5200 × 2) = 10,400 (iii)
Adding (i), (ii), and (iii), we get, 2(A + B + C) = 33,000
Or A + B + C = 16,500
But B + C = 12,500 from Equation (ii)
Hence, A = 16,500 − 12,500 = 4000
