Let weight of cat be -x kgs weight of dog be -y kgs weight of rat be -z kgs From data x+z = 10 ------1 x+y =24 -------2 y+z =20 -------3 Subtract equation 1 frm 2, we get y-z = 14 -----4 Adding equation 3 and 4, we get 2y=34 i.e y=17kgs Put value of y in equation 2, we get x=7kgs Putting value of y in equ 3 gives z=3kgs Hence, weight of cat,dog and rat is 7,17,3 kgs respectively
