  • Question
  • A clock is set at 10 a.m. The clock loses 16 minute in 24 hours. What will be the true time when the clock indicates 3 a.m. on 4th day?


  • Options
  • A. 9 p.m
  • B. 10 p.m
  • C. 11 p.m
  • D. 12 p.m

  • Correct Answer
  • 11 p.m 

    Explanation

    Time from 10 a.m on a day to 3 a.m on 4th day = 24 x 3 + 17 = 89 hours.
    Now 23 hrs 44 min. of this clock = 24 hours of correct clock.
    89 hrs of faulty clock = (24 x 15/356 x 89) hrs = 90 hrs.
    So, the correct time is 11 p.m
