Let the wait of cat,rabbit and dog be x,y,z respectively
acc. to the given conditions;
x+y=10
therefore, x=10y(i)
z+y=20(ii)
x+z=24(iii)
therefore,substituting eqn(i) in eqn(iii);
10y+z=24
therefore'
zy=2410
zy=14(iv)
Adding (ii) and (iv);
z+y=20
zy=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=2417
x=7(vi)
substituting eqn(vi)in eqn(i);
x+y=10
7+y=10
y=107
y=3
weight of dog is 17 kg;
weight of cat is 7 kg ;
weight of rabbit is 3 kg.
hope i helped u:)
