Correct Answer - Option 4 : 44 kg
GIVEN:
Average weight of A, B, C = 56
Average weight of A, B = 52
Average weight of B, C = 54
FORMULA USED:
Average = Sum of observations/Total number of observations
CALCULATION:
Total weight of A, B, C = 56 × 3 = 168 kg ----(1)
Total weight of A, B = 52 × 2 = 104 kg ----(2)
Total weight of B, C = 54 × 2 = 108 kg ----(3)
From (1) - (2) we get,
C = 64 kg
Put C in (3)
B + 64 = 108
B = 44 kg
∴ The weight of B is 44 kg
