Re: 36 small dogs
I can work this out in my head but I don't know if I can explain it properly.OK, it says there are 36 MORE small than large, not that there are 36 small. Which means there are a minimum of 36 small dogs.
To work out how many of each you need to find the mid way point while ensuring 36 is the minimum for small dogs, you minus 36 from 49 which gives 13.
That 13 is then split equally between the small and large dogs, which gives you 6.5 dogs to each side.
So the answer is....Large dogs 6.5....small dogs 36 + 6.5 = 42.5
But without knowing 36 was the wrong answer I wouldn't have worked it out correctly either

Me either!I think it's a bit of a trick question, I remember having something similar for maths homework once and I had no idea how to work it out but fortunately the boyfriend at the time was a year above me at school and a bit of a maths genius.

As the question is worded the answer could be anything between 36 (meaning 13 large dogs) and 49 (meaning 0 large dogs)
And what about medium dogs then? Maybe that's where the half comes in
