    Four bells ring at intervals 4, 6, 8 and 14 s. They start ringing simultaneously at 12 : 00 o' clock. At what time will they again ring simultaneously?

    A)  12 h 2 min 48 s

    B)  12 h 3 min

    C)  12 h 3 min 20 s

    D)  12 h 3 min 44 s

    Correct Answer: A

    Solution :

    LCM of 4, 6, 8 and \[14\text{ }s=168\text{ }s\] \[=2\,\text{min }48\text{ }s\] Thus, they will ring again simultaneously at 12 h 2 min 48 s.
