Actually, as per the direct formula.

The Ratio of torque in case of hollow and solid shafts subjected to the same maximum shear stress.

T(hollow)/T(solid) = (D^4 - d^4)/D^4.
If you substitute in this formula you get exactly 15/16.

Strength of shaft depends upon the section modulus of shaft i.e. π/16 d^3.
Put the values of dia and compare the results.
