Question

find the missing number 4,?, 7, 1, when average means is 6?​

Answer 1

Answer:

12

Step-by-step explanation:

Let the missing number be x,

Mean = 6

n = 4

So, By using the formula, mean = ∑x/n

∑x/n = Mean

or, (4+x+7+1)/4 = 6

or, x+12 = 6*4

or, x+12 = 24

or, x = 24-12

x = 12

Therefore the missing number is 12.

Answer 2

Answer: LET'S TAKE THE MISSING NUMBER AS X.

Step-by-step explanation:

LET'S TAKE THE MISSING NUMBER AS X.

4+X+7+1=6

 12+X/4=6

     12+X=6*4

     12+X=24

     X=24-12

     X=12

 SO THE MISSING NUMBER IS 12.
