    Solution

    ATQ, To find the average of numbers between 9 and 31 that are divisible by 5, we can identify the numbers in that range that satisfy this condition and then calculate their average. The numbers between 9 and 31 that are divisible by 5 are 10, 15, 20, 25, and 30. Now, let's find the average: Average = (10+15+20+25+30)/5 = (100/5) = 20 So, the average of numbers between 9 and 31 that are divisible by 5 is 20.
