Answer 2

Answer:

20

Step-by-step explanation:

The numbers between 6 and 34 which are divisible by 5, are 10, 15, 20, 25 and 30

Average = $\dfrac{Sum\:of\:all\:numbers\:}{Number\:of\:items\:in\:the\:set}$

By using the above formula, let's solve the sum.

$\dfrac{10\:+\:15\:+20\:+25\:+30}{5}$

By addition of numbers in the numerator, we get :-

$\dfrac{100}{5}$

By dividing, we get :-

$\dfrac{\cancel{100}}{\cancel{5}}$ = $\dfrac{20}{1}$

=> 20

∴ The average of 10, 15, 20, 25 and 30 is 20
