Question

If the mean of 10 observation is 100 and each observation is divided by 10 then. Find the new mean​

Answer 1

Hey Mate

Mean = Sum of all observations /  Total No.of observations

75 = Sum / 20

Sum = 75 × 20

Sum = 1500

According to question,

All observations had been divided by 3

So, Sum of all Observations / 3

          = 1500 / 3

          = 500

New Mean = 500 / 20

                  = 25

Mean = 25

Answer 2

Answer:

10

Step-by-step explanation:

let the numbers be x1, x2 ,x3...,x10

mean=100=(x1+x2+x3+..+x10)/10

⇒x1+x2+x3+...+x10=1000

=(x1/10+x2/10+...x10/10)/10

=[1/10(x1+x2+x3+...+x10)]/10

=1/100*1000

=10
