A) 12 o’ clock

B) 16 min past 12

C) 48 min past 12

Ans. C

Time from 8 a.m. on a day to 1 p.m. on the following day = 29 hours.
          24 hours 10 min. of this clock = 24 hours of the correct clock.
          145/6 hrs of this clock = 24 hours of the correct clock.
           29 hours of this clock = [24 * (6/145) * 29] hrs of the correct clock
= 28 hrs 48 min of the correct clock.
          Therefore, the correct time is 28 hrs 48 min. after 8 a.m.
          This is 48 min. past 12.
