a G + b H \to P ro d u c t s

Rate constant

k = [G]^{a} \times [H]^{b}

Overall order of the reaction

= a + b

It is given that rate is increased by 8 times when concentration of both reactants is doubled.

\Rightarrow 8 \times k = [2 G]^{a} \times [2 H]^{b}

\Rightarrow 8 \times k = [2]^{a} \times [G]^{a} \times [2]^{b} \times [H]^{b}

\Rightarrow 8 \times k = [2]^{a + b} \times [G]^{a} \times [H]^{b}

\Rightarrow 8 \times k = [2]^{a + b} \times k

\Rightarrow 8 = [2]^{a + b}

\Rightarrow 8 = 2^{3} = [2]^{a + b}

\Rightarrow a + b = 3

∴

Overall order of the reaction is
