Question
The average of the first six numbers is four times the
average of the next three numbers. If the average of all nine numbers is 24, then find the sum of the last three numbers.Solution
ATQ,
Let the sum of the last three numbers be 'n'.
So, (sum of the first six numbers) ÷ 6 = 4 × (n/3)
Or, sum of the first six numbers = 8n
So, (n + 8n) ÷ 9 = 24
Or, 9n = 216
Or, n = 24
