The average of three integers is 13. When a natural number n is included, the average of these four integers remains an odd integer. The minimum possible value of n is
It is given that average of three numbers is 13.
Sum = 3*13 = 39
It is given, $$\ \frac{\ 39+n}{4}$$ is a odd number.
Minimum value $$\ \frac{\ 39+n}{4}$$ can take such that n is a natural number is 11
$$\ \frac{\ 39+n}{4}=11$$
n = 5
The answer is option C.

Find a number that is divisible by 4 and gives a odd vale.. so if you keep 40 as n it will give product as 10 but if you keep it as 44 it will give product 11 which is odd
