The specific gravity should be in the range of 2.7.

Agree @Walde.

It's 2.7.

Specific gravity 2.65 is correct.

2.7 not correct because it is of fine silt.
Which is generally not settled.

How to solve this? Please explain.

Inorganic solids- 2.6 to 2.9 but generally 2.65 taken and organic solid - 1 to 2.
Generally taken 1.04.
