Let A= Rabbit
B= Cat
C = dog

From Figure above, in simple analysis

A + B = 10kg -----------equation 1

A + C = 20kg -----------equation 2

B + C = 24 kg ---------- equation 3

From equation 2,
A= 20- C

From equation 3

B= 24- C

Substitute A and B into equation 1

20-C + 24-C =10

44-2C = 10

-2C= 10-44

-2C = -34

C= 34/2

C= 17

Substitute C into equation 2

A+ 17 = 20
A= 3

Substitute C into equation 3

B+17 = 24

B= 7

Therefore

A= 3, B= 7, C= 17

Total weight is 3+7+17 = 27

Rabbit= 3kg

Cat = 7kg

Dog = 17kg

it won't get any simpler than this

27

The dog is 17
The cat is 7
The rabbit is 3

Just use deduction, the cat obviously weighs more than the cat.

Work from the answers, take 27 and deduce the weight of each animal.

Lets assume rabbit, cat and dog’s weight are R,C and D correspondingly.

then we can say

Equation 1: R + C = 10

Equation 2: D + R = 20

Equation 3: C + D= 24

Then we need to find value of C + R + D

On adding Equation 1,2 and 3

2R + 2 C + 2D = 54 => R+C+D = 27

chai mathemathician & their long calculation process. that is why maths scare me at times.
very interesting though but i almost confused, i prefer shut cut maths hence i can grab answer & get passing mark grin

Folksyharry:
what will the three animals weigh?

here is just a short cut to the stress.

Dog appeared twice.
Cat appeared twice
Rabbit appeared twice

therefore, (10 +20 + 24)/2 = 54/2 = 27.

Confession: Not by my brain, but by the power and grace to recognize correct answer, and quickly make photocopy.
