Let weight of cat = a weight of rabbit = b weight of dog = c a+b = 10 -------------(1) b+c = 20 -----------(2) c+a = 24 ---------------(3) put a = 10 - b in (3) c+10-b = 24 c-b = 14 --------(4) (2)+(4) 2c = 34 c = 17 weight of dog b = 3 weight of rabbit a = 7 weight of cat

Let the wait of cat,rabbit and dog be x,y,z respectively acc. to the given conditions; x+y=10 therefore, x=10-y------(i) z+y=20-----(ii) x+z=24-------(iii) therefore,substituting eqn(i) in eqn(iii); 10-y+z=24 therefore' z-y=24-10 z-y=14-----(iv) Adding (ii) and (iv); z+y=20 z-y=14 ---------------- 2z=34 therefore z=34/2=17 therefore z=17-------(v) substituting eqn (v)in eqn(ii); x+z=24 therefore, x+17=24 therefore, x=24-17 x=7--------(vi) substituting eqn(vi)in eqn(i); x+y=10 7+y=10 y=10-7 y=3 weight of dog is 17 kg; weight of cat is 7 kg ; weight of rabbit is 3 kg.
