C) \[9:00\text{ }p.m.\]
D) \[8:00\text{ }p.m.\]
E) None of these
Correct Answer: A
Solution :
Explanation Option [a] is correct. Time from 5:00 a.m. on a day to 10:00 p.m. on 4th day is 89 hours. Now, 23 hrs. 44 min. of this clock are the same as 24 hours of the correct clock. i.e., \[\frac{356}{15}\]hrs. of this clock = 24 hrs of correct clock. \[\therefore \] 89 hrs. of this clock \[=\left( \frac{24\times 15}{356}\times 89 \right)\] hrs. of correct clock = 90 hrs of correct clock. So, the correct time is 11:00 p.m.
