Recently Mr. And Mrs. Crazy have heard the news about the petrol shortage. The king has introduced to the villagers petrol rationing according to the following system, based on the 3-digit number of each number-plate (000 to 999) of the cars in the village.

People could only buy petrol on certain days as follows:
Sunday: if each of the three digits was less than 6
Monday: if the 3-digit number was odd
Tuesday: if the sum of the three digits was greater than 10
Wednesday: if the 3-digit number was a multiple of 3
Thursday: if the sum of the three digits was less than 15
Friday: if at least two of the three digits were the same
Saturday: if the 3-digit number was less than 500

If Mr. and Mrs. Crazy could refuel their car on any day of the week, what is the number on their car's number-plate?
