Explanation:

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.
• 24 hours 10 min= $24\frac{10}{60}=24\frac{1}{6}=\frac{145}{6}$

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.

Hence, option 2 is the correct answer.
