>>11785762After a quick nap I realised I was wrong. I got this:
>The child in front (the shortest) is holding neither a red nor blue balloonThis eliminattes those two, and moreover
>in front of the child with the yellow balloonthis tells us that yellow can't come first either. The only possibility is white first!
>Tessie sees exactly two balloons in front of herTessie is third. Combining this with
>Susie is holding a red balloonSusie is second and then the last two balloons are blue and yellow, or Susie is last and the balloons are WBYR.
Now, if Susie is the second one, we know the balloons WRBY. Moreover, we have 1ST4, and then
>Amy is in front of Tessiegives 1=A and 4=E, and thus
ASTE
WRBY
If Susie is the last one, then we know
12TS
WBYR,
but there is no way to decide whether Amy or Eddie comes first. If this is supposed to have a solution, then the order is A&W, S&B, T&Y, E&Y.
I have no idea what this plan is supposed to be, but maybe trying to eliminate wrong options.
