Let the respective weights of the rat, cat and dog be represented by a, b and c.
Then from the 1st image,
a + b = 10kg .................eq.1
From the 2nd image,
a + c = 20kg .................eq.2
And from the 3rd image,
b + c = 24kg .................eq.3
Now, eq.2 - eq.3 gives
a - b = -4kg ..................eq.4
eq.1 + eq.4 gives
2a = 6kg :. a = 3kg
From eq.1,
b = 10kg - a
:. b = 10kg - 3kg = 7kg
From eq.2,
c = 20kg - a
:. c = 20kg - 3kg = 17kg
Now the 4th image shows
a + b + c = 3kg + 7kg + 17kg = 27kg
Final answer 27kg
THANK YOU.

Your topic has the potentials of coming to the fp if you had attracted many more posts within few hours of posting the topic. This I expected you to do by responding to my post immediately, even if it means not acknowledging the correctness of my solution and thereby attracting hot argument and more solutions and explanations.
I commend your interest in Maths. Wishing you great success in your studies.
