The mean of set of n numbers when each in divided by 5 is X 5 , then mean of the n number is

Options

  1. A5 X
  2. BX
  3. C25 X
  4. Dx 25

Correct answer

B. X

Step-by-step solution

Mean of n number when each is divided by 5 is x 5 . Let x₁, x₂, x₃, , x_n are the number. Given mean = Sum of observation Total number of observation aligned X 5 & = x 5 + x₂ 5 + x₃ 5 + + x_n 5 n X 5 & = 1 5 (x₁+x₂+x₃+. .+x_n ) n X & = x₁+x₂+x₃+ +x_n n aligned Mean of x₁, x₂, x₃, , x_n is X .
