A ternary blend of gasoline $($octane number $=90),$ alcohol $(75\%$ ethanol, $25\%$ methanol$),$ and benzole

$(75\%$ benzene, $15\%$ toluene, and $10\%$ xylene$)$ is burned completely in $35\%$ excess $O_2.$ Analysis of the

blend shows $70\%$ gasoline, $15\%$ benzole, and $15\%$ alcohol. Calculate the complete analysis of the

exhaust gas.
