    Solution:

    We are asked to find the mean of odd natural number so we will first find the six odd natural numbers and since these numbers are not divisible by 2 then these numbers can be
    N= {1, 3, 5, 7, 9, 11}
    Now we will find the sum of these odd natural numbers, hence we get sum
    ⇒S=1+3+5+7+9+11=36
    Now since the mean of natural numbers is the ratio of the sum of natural numbers by total numbers so we can write the mean of these six odd natural numbers whose sum is equal to 36 as
    Mean=366=6
    Hence, the mean of first six odd natural numbers= 6
    So, the correct answer is “6”.
