Y = Yw*(G+e*Sr)/(1+e).

Put e*Sr = W*G.

Y = Yw*(G+G*W)/(1+e).

Put values: e = 0.56.

Sr = W*G/e.
Sr = 92%

Look at the units.Unit weights are given in g/cm^3 and unit weight of water is 1 g/cm^3 in CGS system.

@Souvik.

If we use that formula, we get e = 0.6.

By using Gw=Sr.e. We get Sr = 86.6%.

Yes @Priyanka.

I'm getting the same answer can anyone justify why Yw =1 not 9.81?

According to me, 77 is the correct answer.

b=G*w(1+w)/(1+e).
e=.56.
Sr=wG/e=92%.
