Can you find the largest possible number containing any 9 of
the 10 digits, considering 0 also as a number that is divisible by 11, without
a remainder?
Answer: From the Jews abode
the Christian and the Turk set out on a tour round the world, the Christian
going due east and the Turk due west. This way the Christian gains a day and
the Turk loses a day. So that when they meet again at the house of the Jew
their reckoning will agree with his and all three may keep their Sabbath on the
same day.
