Question
The average weight of five students in a class is
recorded as 58 kg. Two of the students have weights of 48 kg and 54 kg, but their actual weights are 45​ and 67​ of their recorded weights, respectively. What is the actual average weight of all five students?Solution
Actual weight of the 1st student = (5/4) × 48 = 60 kg Actual weight of the 2nd student = (7/6) × 54 = 63 kg Actual average = (58 × 5 – 48 – 54 + 60 + 63)/5 = 62.2 kg
