The reaction between X and Y is first order with respect to X and zero order with respect to Y.

Experiment	$\frac{\left[\text{X}\right]}{{\text{mol\hspace{0.17em}L}}^{-1}}$	$\frac{\left[\text{Y}\right]}{{\text{mol\hspace{0.17em}L}}^{-1}}$	$\frac{\text{Initial\hspace{0.17em}rate}}{{\text{mol\hspace{0.17em}L}}^{-1}{\min }^{-1}}$
I	0.1	0.1	$2\times {10}^{-3}$
II	L	0.2	$4\times {10}^{-3}$
III	0.4	0.4	$\text{M}\times {10}^{-3}$
IV	0.1	0.2	$\text{2}\times {10}^{-3}$

Examine the data of table and calculate ratio of numerical values of M and L. (Nearest Integer)
