    English Medium Answer
    First The bell ring together at 9:00 am
    So they next ring together at
    First Bell ring at the interval of 12 min
    Second Bell ring at the interval of 15 min
    Third Bell ring at the interval of 18 min

    LCM of 12min,15min,18min = 180 min

    1min = 1/60 hours
    180min = 180/60 = 3 hours

    9:00 am + 3 hours = 12:00 pm

    So they next ring together at 12:00pm

    Hindi Medium Answer
    सबसे पहले सुबह 9:00 बजे एक साथ घंटी बजती है
    तो वे अगली बार एक साथ बजे
    पहली घंटी 12 मिनट के अंतराल पर बजती है
    15 मिनट के अंतराल पर दूसरी घंटी बजती है
    18 मिनट के अंतराल पर तीसरी घंटी बजती है

    12मिनट,15मिनट,18मिनट का एलसीएम = 180 मिनट

    1 मिनट = 1/60 घंटे
    180मिनट = 180/60 = 3 घंटे

    9:00 पूर्वाह्न + 3 घंटे = 12:00 अपराह्न

    तो वे अगली बार दोपहर 12:00 बजे एक साथ बजेंगे
