14% of 14 + 28% of 28 + 92% of 96 - 15% of 85 = ?

It is given that,
(14% of 14) + (28% of 28) + (92% of 96) - (15% of 85) = ?
$$\left( ? \right) = \left( {\frac{{14 \times 14}}{{100}}} \right) + \left( {\frac{{28 \times 28}}{{100}}} \right) + $$       $$\left( {\frac{{92 \times 96}}{{100}}} \right) - \left( {\frac{{15 \times 85}}{{100}}} \right)$$
$$\eqalign{ & \left( ? \right) = \left( {1.96 + 7.84 + 88.32 - 12.75} \right) \cr & \left( ? \right) = \left( {98.12 - 12.75} \right) \cr & \left( ? \right) = 85.37 \cr} $$
