5. None of the above/More than one of the above.

Answer 1

Correct Answer - Option 4 : 111 kg

Given:

The average weight of 21 workers in the shop 45 kg, If the weight of the Shop manager is included, the average is increased by 3 kg

Calculation

The average 21 workers = 45

∴ Total weight = 45 × 21 = 945

Then the average weight of the Manager = 48

∴ Total weight = 48 × 22 = 1056

Hence, the average weight of the manager of the shop = 1056 - 945 = 111 kg
