okies....

SNOWY, a 4 year old male white horse lost last year.

The Derby is for three year old horses. Therefore only a current four year old horse could have lost last year.

SNOWY is the only horse which could have been three last year (four this year).

The farm is preparing three of the seven horses for this years Derby.....there must therefore be at least three 3-year old horses among the seven. BILLY is 3-years old.....necessarily, BEAUTY and her cousin LUCKY must be 3 years old both. ( they are of the same age)......
Beauty's mum could not be three because she won in the Derby before. The oldest black is even older than BEAUTY's mum.
BEAUTY's aunt could not be three......... if she were, then SNOWY must also be three to complete the three entries this year. This would mean that no horse would be four years old as BEAUTY and LUCKY would be one and a half years old.

does that make sense ????



I think I've lost the plot now with all that typing....

edit:.... left a bit of the explanation out ... realised when I read it back... d'oh

[ilw]

Can the horses be too old to enter or not be prepared to enter despite being old enough? if not its gotta be the oldest black stallion, if they can be too old or chosen not to enter then it must be the horse of unknown colour.
The name I dunno
Edit: doh. i took it to mean that they had to be 3 or older damn

1^2 + 4 ^ 3= 65

wtf???

[dwightfry]

wtf???
that still equal 55

^ = to the power of

1^2 = 1 X 1 = 1

4^3 = 4 X 4 X 4 = 64

1 + 64 = 65

[ilw]

4^3 = 64 not 54
