The average weight of 10 boys is 70 kg. But later, it was found that at two places the weight 54 kg was read as 44 kg and at one place weight 35 kg was read as 40 kg. Find the correct average weight (in kg).
Answer (2)
The correct average weight = 71.5 kg
;
The correct average weight of the 10 boys is 71.5 kg, determined by first calculating the total weight based on the given average and then correcting for the misread weights. Initially, the total weight was found to be 700 kg, but after adjusting for the misreads, the correct total became 715 kg. The average was then calculated from this corrected total.
