If the average of all numbers between 6 and 34 which are divisible by 5; then it is:

🧠 Explanation:

The average of numbers between 6 and 34 divisible by 5 (10, 15, 20, 25, 30) is 20. Add them (10 + 15 + 20 + 25 + 30 = 100), then divide by 5 (100 ÷ 5 = 20). This helps students practice averages and divisibility in math.
