>>11933628Pair of shoes = 10, guy with whistle = 5, pair of whistles = 4.
Is the last line just meant to be an absolute statement?
Or are we meant to answer it as:
(10/2)+(5-(4/2))*(4/2) = 11?
Because pretty sure a pair of shoes will cost differently to two single, likely unpaired shoes[1], the guy's ability to blow can be judged regardless of the number of whistles around his neck[2], and whistles often come as a buy-one-get-one-free deal.
11/10, got me to reply.
[1] Although, judging by the pictographs on top, chances are there is only one shoe model, so probability of not pairing is reduced
[2] Evebn without any! Proof left as exercise.
