Question
In a set of 10 data points, the average of the first three
numbers is 12 and the average of the last five numbers is 27. If the average of the 4th and 5th numbers is 15, calculate the average of all ten numbers.Solution
ATQ,
Average of all the 10 numbers = {(3 × 12) + (5 × 27) + (2 × 15)/10}
= {(36 + 135 + 30)/10} = 201/10 = 20.1
