$\gamma_{1} A +\gamma_{2} B \rightarrow \gamma_{3} C +\gamma_{4} D$
Concentration of $C$ changes from $10\, mmol$ appearance of $D$ is $1.5$ times the rate of disappearance of $B$ which is twice the rate of disappearance $A$. The rate of appearance of $D$ has been experimentally determined to be $9 \,m\,mol$ $dm ^{-3} s ^{-1}$. Therefore the rate of reaction is $......\,m\,mol\, dm ^{-3} \,s ^{-1}$. (Nearest Integer)
