डिजिटल घड़ी की उलझन... (The digital clock problem...)

विशेष नोट : अगर आप जवाब ढूंढ लेते हैं तो ठीक, वरना कमेंट लिख दीजिएगा, मैं जवाब आपको मेल के जरिये भेज दूंगा...

एक दिन के पूरे 24 घंटों के दौरान 12 घंटे वाली किसी डिजिटल घड़ी में कोई भी तीन अंक एक साथ (उदाहरण के लिए 1:11, 11:12, 12:22 आदि) कितनी बार लिखे हुए दिखेंगे...?

Now, the same riddle in English...

Special Note: If you succeed in solving this one, well and good; but in case, you don't, just leave a comment, and I will mail the answer to you...

During the 24 hours of a day, how many times would the same three digits in a row (for example 1:11, 11:12, 12:22 etc) be displayed on a 12-hour digital clock...?
