zero marks.
failed to answer the question.
I shouldn't have spent 10 minutes trying to work that out with algebra and a lot of swearing, but I resign to the fact that my brain doesn't work that way...Quote:

That's as far as I got.
How did you work it out ron?
The answer is clearly an unspecified amount of flying fur when the animals finally work out what's reflected in the glass.

(R-C)+(R+C)=2R= -4+10=6
R=3
3+C=10
C=10-3
C=7
D=20-R=20-3
D=17
R+C+D=27
less chance of making a mistake
R+C=10
R+D=20
C+D=24
add all equations together
R+C+R+D+C+D=10+20+24
2R+2C+2D=54
divide by 2
R+C+D=27
R+C+R+D+C+D=54Quote:

A tennis championship is played on a knock-out basis, i.e. a player is out of the tournament when he loses a match.
if the championship starts with 100 players, how many games are played?
I is raining so none :D
