Big Bobbie had bun problems, here’s the solution.
If Big Bobbie labelled his bun machines 1 to 10 then took 1 bun from machine 1 and 2 buns from machine 2, then 3 buns from machine 3 and so on up to machine 10 he would be able to weight them all at once, thus using his scales once only. If the load was 4g light then machine 4 is the culprit, likewise if the load was 9g light, then machine 9 is the faulty one.
A simple yet elegant solution don’t you think ?
