Correct Answer - Option 4 : 194 kg
Given:
The average weight of 8 persons sitting in a boat is 68 kg. The average weight of the boat and the persons sitting in the boat is 82 kg
Concept used:
Average = (Sum of observations)/(Number of observations)
Calculation
Weight of the boat = 9 × 82 – 8 × 68
= 738 – 544 = 194 kg
∴ The weight of the boat is 194 kg
