Find the Average of All the Numbers Between 6 and 34 Which are Divisible by 5.

Answer: (2) 20
Explanation:-
The numbers between 6 and 34 which are divisible by 5 = 10, 15, 20, 25, 30
Formula-
Average = The sum of observation/the number of observation
Then, the average = (10 + 15 + 20 + 25 + 30)/5
= 100/5
= 20
Hence, the answer is (2) 20.
