\mathrm{\therefore \text { mass } \% \text { of methane in the mixture } \Rightarrow}

\begin{aligned} & \Rightarrow \frac{65 \times 16}{35 \times 4+65 \times 16} \times 100 \\ & \Rightarrow \frac{1040}{140+1040} \times 100 \end{aligned}

\begin{aligned} & \Rightarrow \frac{1040}{1180} \times 100 \\ & =.88 \% \end{aligned}
