In an aircraft, there are 25 passengers and the following table shows the number of passengers and their corresponding weights. No of passengers 4 5 6 5 3 2 Weight in  kg 90 60 75 78 72 45 What is the approximate average weight of all the 25 passengers? Correct Answer 72 kg 

Total weight = 4 × 90 + 5 × 60 + 6 × 75 + 5 × 78 + 3 × 72 + 2 × 45 = 1806 

Average weight = Total weight / total number of passenger = 1806 / 25 = 72.24 

So here 72 is the approximate weight.

Hence, option 3) is the correct answer.
