Solution

The correct option is B
5.5

The first 10 natural numbers are 1 to 10.

Sum of first 10 natural numbers $= (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10)$

So, Sum of first 10 natural numbers is 55

$M e a n = \frac{S u m o f a l l t h e g i v e n q u a n t i t i e s}{N u m b e r o f q u a n t i t i e s}$

$M e a n = \frac{55}{10} = 5.5$
