The first thing to notice is that numbers in purple are greater than 12 and numbers in green are less than 13. Now before focusing in on the letter A take a look at some of the outer circles that are a bit less jumbled. Can you find any concept or pattern that starts to stick out? The numbers are on the inside edge of the circle. Hopefully the idea of a clock comes to mind. The bottom right circle contains a 3 right where 3 is on a typical clock. If you carry this concept to the purple numbers you can see it is still based on a clock but that purple is a 24 hour clock. So green numbers represent as 12 hour clock and purple numbers represent a 24 hour clock. You can now look at the circle that A is in and figure out that A is in place of 10:00.
