Here is complete explanation of The average weight of three boys A B and C is….

Solution(By ExamCraze Team)

Total weight of (A + B + C)
=( $$54frac{1}{3}$$ × 3 ) kg
= 163 kg
Total weight of (B + D + E)
= (53 × 3) kg
= 159 kg
Adding both, we get:
= A + 2B + C + D + E
= (163 + 159) kg
= 322 kg
So, to find average weight of A, B, C, D and E, we ought to know B's weight, which is not given.
So, the data is inadequate.
