Question:
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)?
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)?
Show Hint
Sum of deviations from the mean is always zero.
Updated On: Mar 20, 2026
- \(M\)
- \(a+b+c+d+e\)
- \(0\)
- 5M
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Given mean M=(a+b+c+d+e)/(5)⟹ a+b+c+d+e=5M.
Step 2: (a+b+c+d+e)-5M=0
