Question
There are ten numbers. The average of the first three
numbers is 11, and the average of the last five numbers is 24. If the fourth and fifth numbers average 19, what is the overall average of all ten numbers?Solution
ATQ,
Average of all the 10 numbers = {(3 × 11) + (5 × 24) + (2 × 19)/10}
= {(33 + 120 + 38)/10} = 191/10 = 19.1
