Question

Average of multiples of 3 between 10 and 20

Answer 1

Step-by-step explanation:

Multiples of 3 between 10 and 20 is 12, 15 and 18

average= sum of numbers/total numbers

= 12+15+18/3

=45/3

=15

Average of multiples of 3 between 10 and 20 is 15

Answer 2

The average of the multiples of 3 between 10 and 20 is 15.

Given:

The number 3 and the range 10 to 20.

To Find:

The multiples of 3 between 10 and 20 and their average value.

Solution:

• A multiple is produced when a number is multiplied by an integer.
• The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.
• It is fairly simple to calculate the average of a set of numbers or values.
• The only thing we have to do is to add up all the numbers and divide the total by the number of values provided.

For the given question, first we have to find the multiples of 3 in the given range.

So, multiples of 3 between 10 to 20= 12,15,18

Total number of values= 3

Average of the values= (12 + 15 + 18)/ 3 = 45/3 = 15

Hence, the average of the multiples of 3 between 10 and 20 is 15.
