Let rabbit=r,dog=d,cat=c,

According to the question,

r+c=10

d+r=20

d+c=24

On adding the above three equations;

r+c+d+r+d=c=10+20+24

2(d+c+r)=54

d+c+r=54/2

d+c+r=27

Thus,weight of dog+weight of cat+weight of rabbit=27 kg

Hope I helped!

sorry ...
this is the correct solution :Let rabbit=r,dog=d,cat=c,

According to the question,

r+c=10

d+r=20

d+c=24

On adding the above three equations;

r+c+d+r+d=c=10+20+24

2(d+c+r)=54

d+c+r=54/2

d+c+r=27

Rabbit be r
cat be c
dog be d
r+c=10 kg(given)........1
d+c=20...2
d+r=20............3
adding 1 ,2 and 3 we get

so2( c+r+d)=24+20+10
so they all weigh =24+20+10/2
54/2
=27
