Munish's watch loses 6 minutes per day. On Monday morning at 11 o'clock it is 45 minutes ahead of the actual time. How much more time should Munish's watch lose, so as to indicate the correct time on Saturday evening at 5 o'clock?

From Monday 11 a.m. to Saturday 5 p.m. is a total of 126 hours, which is 5.25 days. At a rate of 6 minutes lost per day, the watch will naturally lose 31.5 minutes over this period. To change the current 45 minutes fast to the correct time, the watch must lose exactly 45 minutes, so it needs to lose an additional 13.5 minutes.
