A completely mixed reactor $)=(1000m^3$ is receiving $15,000\frac{L}{m}in$ wastewater stream with a pollutant concentration of $100k\frac{g}{m^3}.$ There is another $5\frac{m^3}{m}in$ influent from an adjacent factory that has $0\mathrm{.}5k\frac{g}{m^3}$ pollutant. $75\%$ of pollutants are biologically removed in the reactor. To prevent overloading, the operator decided to bypass $5\%$ of wastewater flow and have it mixed with effluent $Q_3$ and $C_3).$ Calculate $Q_3$ in $\frac{L}{s}$ and $C_3$ in $k\frac{g}{m^3}.(*$Answer in whole number only, No unit$)$

$Q_3=[a]\frac{L}{s}$;$C_3=[b]k\frac{g}{m^3}$
