Question

the sum of 11 numbers is 132.Find their average. please is question ka answer btado koi​

Answer 1

Answer:

12

Step-by-step explanation:

Now to find the x, we have eliminate 11 which is in multipication relationship with x. So we have to use inverse operation of multiplication i.e., division.

We should not forget about equality i.e., when we divide 11 on left hand side of the equation, we have to do the same on right hand side to maintain equality, else equality will be destroyed.

Therfore dividing by 11 on both side of the equation,

(11*x)/11 = 132/11

which get reduced to

1*x = 12

which is x = 12.

You can double check this :

A number times 11 is 132 is the question.

12 times 11 is 132.

So the number is 12.

Answer 2

Average of numbers or mean = (Sum of observations / no. of observations )
Here , sum of observations = 132
And number of observations = 11
So, average or mean = 132/11 = 12 (answer)
