The arithmetic mean of numbers a, b , c , d , e is M . What is the value of (a-M)+(b-M)+(c-M)+( d - M )+( e - M ) ?

Options

  1. AM
  2. Ba+b+c+d+e
  3. C0
  4. D5 M

Correct answer

C. 0

Step-by-step solution

Given M = a + b + c + d + e 5 a+b+c+d+e=5 M a+b+c+d+e-5 m=0 array l (a-M)+(b-M)+(c-M)+(d-M) +(e-M)=0 array Hence, required value =0
