Question
The average weight of 32 dogs was
initially computed to be 45 kg. However, it was later discovered that the weights of two dogs were incorrectly recorded as 47 kg and 64 kg instead of their actual weights of 70 kg and 57 kg. Determine the corrected average weight.Solution
ATQ, Sum of weight of 32 dogs calculated, initially = 32 × 45 = 1440 Corrected sum = 1440 – 47 – 64 + 70 + 57 = 1456 Therefore, required average = 1456/32 = 45.5 kg
