1.6 = (1*2.56)/(1+e);
e = 0.6;
n = e/1+e;
n = 0.6/(1+0.6);
Then n = 0.375.
e = 0.6;
n = e/1+e;
n = 0.6/(1+0.6);
Then n = 0.375.

rd=1.6g/cc ,r=1.84g/cc relation is rd=r/1+w.
We get water content w= 0.15.
We get water content w= 0.15.

Instead of 1.84 take the standard value of density of water that is 1g/cc.

The water density is given as 1.84 g/cc , then how the answer is 375?

Then what about the value of water density or what does that signify?

Both are right @Rubby and @Reddy.
The void ratio is (e).
The void ratio is (e).

If we take water density 1.84 then porosity will be 0.66.

I think it should be the wet density of the soil sample.
Ravi said:

If water density is considered the answer must be .66.
Abhik said:

By using the density of water the answer is 0.66.
