Question

the sum of 6 numbers is 210.Find their average.If one of the number is 36.Find the average of five numbers.

Answer 1

Given,

The sum of 6 numbers is 210.

One of the number 36.

To find,

Average of the first 6 numbers.

Average of the last 5 numbers.

Solution,

First of all, we have to calculate the average of the first 6 numbers, by using the following mathematical formula,

Average = (Sum of 6 numbers / Total numbers) = 210/6 = 35

Now,to find the average of last five numbers, we have to calculate the sum of the last five numbers.

Sum of last 5 numbers = Sum of 6 numbers - 6th number = 210-36 = 174

Average of last 5 numbers = 174/5 = 34.8

Hence, average of first 6 numbers 35 and the average of last 5 numbers 34.8
