X and Y-co-ordinate of Centre of mass are given as
 
begin mathsize 12px style straight X equals fraction numerator straight m subscript 1 straight x subscript 1 plus straight m subscript 2 straight x subscript 2 over denominator straight m subscript 1 plus straight m subscript 2 end fraction end style
begin mathsize 12px style straight y equals fraction numerator straight m subscript 1 straight y subscript 1 plus straight m subscript 2 straight y subscript 2 over denominator straight m subscript 1 plus straight m subscript 2 end fraction end style
 
 
Assuming them on x and y-axis
