    At 5 O' clock, the minute hand is 25 min space apart. The two hands will be 5 min apart between 5 and 5 : 30, if the minute hand is (25 - 5) i.e, 20 min spaces behind the hour hand.
    Now, 55 min are gained in 60 min.
    20 min are gained in = (60/55 x 20) = (240/11) = 219/11 min
    So, the hands will be 5 min apart at 219/11 min past 5.

    Total hours from 6 : 14 am morning to evening 6 : 14 pm = 12 h and total hours from 6 : 14 pm evening to 8 : 02 pm evening = 8 : 02 - 6 : 14 = 1 : 48 h i.e., 1 h and 48 min

    Correct Option: C

    Total hours from 6 : 14 am morning to evening 6 : 14 pm = 12 h and total hours from 6 : 14 pm evening to 8 : 02 pm evening = 8 : 02 - 6 : 14 = 1 : 48 h i.e., 1 h and 48 min

    ∴ Total hours and minutes
    = 12 h + 1 h 48 min
    = 13 h and 48 min
