    Two pipes A and B can fill a tank in 20 hours and 24 hours respectively. If the two pipes opened at 5 in the morning, then at what time the pipe A should be closed to completely fill the tank exactly at 5 in the evening?  
    दो पाइप A और B क्रमश: 20 घंटे और 24 घंटे में एक टंकी भर सकते हैं। यदि दो पाइप सुबह 5 बजे खोले जाते हैं, तो शाम के ठीक 5 बजे टंकी पूरी तरह से भरने के लिए पाइप A को कितने बजे बंद किया जाना चाहिए? 

    Options :-

    1. 3 pm 
      3 बजे 

    2. 2 pm 
      2 बजे 

    3. 1 pm
      1 बजे  

    4. 11 am 
      11 बजे
