That should do for a while.

PhilW wrote:A mathematical port fanatic keeps his port in a (temperature and humidity controlled) safe, the key to which is an electronic 6-digit PIN. As he cannot reliably remember this PIN, he has worked out that with each letter representing a different number, he can add three port houses with the total being a fourth, this total being a six digit number. Unfortunately, he has forgotten one of the port houses. He remembers this:

Code: Select all

   CALEM
   ?????
+ OFFLEY
  ------
= TAYLOR

Determine the missing port name and the sum and hence identify the PIN to the safe to allow access to the port!

All shippers are technically Portuguese, aren't they?
