A new subdivision is being constructed, along a long road with hundreds of houses. The houses are all numbered in order starting with 1 – so they proceed 1, 2, 3, 4, … down the long road. All of the people go to the hardware store to buy numbers for their mailbox, and they line up in order at the counter. The store, unfortunately, has only 100 of each digit available.

Which homeowner will be the first who cannot buy the complete number for his mailbox?

162 (i think)

every number (1-9) is used 20 times for numbers 1-99.

100 - 199 uses the number one 100 times. All of the other numbers are used only 20 times again.

1 - 161 uses 100 ones.
