Question

Average of 8 numbers is 10. Sum of those 8 numbers is​

Answer 1

Answer:

Let sum of 10 numbers is x.

We know that ,

(sum of all numbers ÷total given number)=average

So, x÷10=8.

x=80. Now if each number is multiply by 5 then we can have 5 as common multiple of 80.

S0, 5*x/10=new average

New average=5*80÷10 which is equal to 40.

Hence New average is 40

Answer 2

Sum of those 8 numbers is 80

Given : Average of 8 numbers is 10.

To find : Sum of those 8 numbers.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the sum of those 8 numbers)

Here, we will be using the following formula.

Sum of N number of terms = Average of N number of terms × N

In this case,

• N = 8
• Average of the 8 numbers = 10

So, by putting the available data in the above mentioned mathematical formula, we get :

Sum of 8 numbers = 10 × 8 = 80

(This will be considered as the final result.)

Hence, the sum of those 8 numbers is 80
