Solution
Using simple logic: Imagine the animals all raise one leg. When this is done, there will be a total of 80 – 28 = 52 legs visible. Then imagine each of the animals raising a second leg, then there will be 52 – 28 = 24 legs left. Since the chickens have only two legs, all the 24 legs must belong to the rabbits. Now since the rabbits have already raised two legs, then each of the rabbits must be contributing 2 legs to the 24. Therefore there are 24 divided 2 = 12 rabbits. Therefore, since there are 28 animals in total, then there are 28 – 12 = 16 chickens.

Format mathematics method:
Let X be the number of Chickens and Y be the number of Rabbits. Here is the formal mathematical approach.
X + Y = 28 (1)
2X + 4Y = 80 (2)

Multiply eq.1 by 4:
4X + 4Y = 112 (3)
Subtract eq.2 from eq. 3:
2X = 112 – 80 => 2X = 32 => X = 16 therefore Y = 28 – 16 = 12.

y am i. . .


why am i having this feeling that @ YungMillionaire and @AkinPhysicist are one and the same person - trying to attract attention to himself

meanwhile this reasoning question has been there for ages and was copied and modified its called "the head and leg logic reasoning". google has it.

bia forget dat thing. They are not the same. That Akin na sharp guy. I once posted a topic on Biafra and 2 minutes after I posted the guy replied with two solid paragraphs of anti-Igbo nonsense. The guy is an Igbo-hater but he is very smart. I suspect he uses dictation apps.

lol how can you sound so confident? I challenge you to a test!.
Is there any online competition we could do? Maths btw.

Please don't derail this thread. See my post above as to how Akin solve this so quickly. I don't have time for childish games.
