A watch is 1 minute slow at 1 pm on Tuesday and 2 minutes fast at 1 pm on Thursday. When did it show the correct time = ?
A. 1 : 00 am on Wednesday
B. 5 : 00 am on Wednesday
C. 1 : 00 pm on Wednesday
D. 5 : 00 pm on Wednesday
Answer: Option B
Solution (By Examveda Team)
Time from 1 pm on Wednesday to 1 pm on Thursday = 48 hoursSo, the watch gains (1 + 2) minute or 3 minutes in 48 hours.
Now, 3 minutes are gained in 48 hours
So, 1 minute is gained in $$\left( {\frac{{48}}{3}} \right)$$ = 16 hours.
Thus, the watch showed the correct time 16 hours after 1 pm on Tuesday, i.e., 5 am on Wednesday
