The 10 past 10 is actually a 'tick' sign recognized universally, meaning PASS. Each clock or watch has to go through a QC test. The first guy in the assembly line will put the battery in and check to see if the clock/watch is functioning. If it does, he will remove the battery and adjust it to 10 past 10, showing that it's passed. Those malfunction ones will be simply set to other times. The next guy in the line will pack only those clocks/watches showing 10 past 10.
How do you rate my explanation?
I was given this 10/10 puzzle by a friend of mine from India about 12 years ago. I gave him my explanation within 5 minutes right on the spot. Another friend of mine said I'm knowledgeable, outspoken, and quick-thinking.
