Question

What is the mean of first 10 natural numbers

 A) 5

B) 5.6

C) 5.5

D) 5.4

Answer 1

Correct option is C) 5.5

First 10 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

\(\therefore\) sum of first 10 natural numbers = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55

\(\therefore\) Mean Average = \(\frac{Sum}{10}=\frac{55}{10}\) = 5.5
