Question
A list contains ten numbers. The average of the initial
three values is 14, and the last five numbers have an average of 23. If the middle two numbers (4th and 5th) have an average of 16, determine the average of all ten numbers.Solution
ATQ,
Average of all the 10 numbers = {(3 × 14) + (5 × 23) + (2 × 16)/10}
= {(42 + 115 + 32)/10} = 189/10 = 18.9
