घड़ी की सुइयां और रेखागणित... (Hands of a clock at geometry...)

कुछ साथियों और मित्रों की फरमाइश पर कुछ आसान प्रश्न भी डाल रहा हूं...
As requested by a few of my friends and colleagues, am putting a few of easy ones...

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

दोपहर बाद 1515 बजे, और फिर रात को 2145 बजे किसी घड़ी की तरफ देखें...

...और अब मुझे बताइए, दोनों समय मिनट और घंटे की सुइयों के बीच के कोण क्या होंगे...?

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...

Look at a clock in the afternoon at 1515 hours, and then at night at 2145 hours...

Now, tell me, what would be the angles, at both the times, between the hour and the minute hands...?

  6. मुझे लग रहा है कि ईशा आज तुक्के मारने के मूड में है, सवाल हल करने के मूड में नहीं... अफसोस, यह दोनों जवाब भी सही नहीं हैं...
