Puzzle 281 


Painter Pete, our local DIY expert, is renovating the local hospital.

He has to number each of the rooms in the hospital with plastic numbers.

However, he has run out of the number 9.

Unfortunately, he has no spare 6's available, which certainly would have been useful.

How many 9's must Pete buy in order to number all 1,000 rooms?
