The composition and energy content of a representative solid waste sample are given in the table. If the moisture content of the waste is 26%, the energy content of the solid waste on dry-weight basis is ________ MJ/kg (round off to one decimal place).

$$ \begin{array}{|c|c|c|} \hline \text { Component } & \text { Percent by mass } & \text { Energy content as-discarded basis (MJ/kg) } \\ \hline \text { Food waste } & 20 & 4.5 \\ \hline \text { Paper } & 45 & 16.0 \\ \hline \text { Cardboard } & 5 & 14.0 \\ \hline \text { Plastics } & 10 & 32.0 \\ \hline \text { Others } & 20 & 8.0 \\ \hline \end{array} $$
