It is not air content on the LHS, it is a percentage of air voids.

Actually,
ac + sr = 1.
Hence, ac = 1 - sr.
But here, if we resolve the eq in the ans, we will get;
ac = n(1-sr).
Is this valid?
ac + sr = 1.
Hence, ac = 1 - sr.
But here, if we resolve the eq in the ans, we will get;
ac = n(1-sr).
Is this valid?

Here given C and D answer are same so which are correct?

Actually, it is not air content it is percentage air void.
na= n*ac.
& ac= 1-Sr.
na= n*ac.
& ac= 1-Sr.

Actually, there in place of ac it should be na.

Actually here is not air content, here is air voids.
ac+Sr=1, ac=1-Sr.
Na=ac*n, n=e/1+e.
Na=e(1-Sr)/(1+e).
ac+Sr=1, ac=1-Sr.
Na=ac*n, n=e/1+e.
Na=e(1-Sr)/(1+e).

@Anees Kumar,
What is Na?
What is Na?

The percentage of air voids should be on LHS which is equal to porosity*air content, air content is equal to 1-S, porosity = e/1+e.

This is not air content this is % air voids.
