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

Experiment	${{[X]} \over {mol\,{L^{ - 1}}}}$	${{[Y]} \over {mol\,{L^{ - 1}}}}$	${{Initial\,rate} \over {mol\,{L^{ - 1}}\,{{\min }^{ - 1}}}}$
I	0.1	0.1	$2 \times {10^{ - 3}}$
I	L	0.2	$4 \times {10^{ - 3}}$
III	0.4	0.4	$M \times {10^{ - 3}}$
IV	0.1	0.2	$2 \times {10^{ - 3}}$

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