(A) Total time elapsed from $5$ pm Tuesday to $11$ pm Wednesday is $30$ hours.In this duration,the watch gained a total of $3 + 5 = 8$ minutes.The watch shows the correct time when it covers the $3$ minutes it was initially slow.Since the watch gains $8$ minutes in $30$ hours,it gains $1$ minute in $\frac{30}{8}$ hours.Therefore,it gains $3$ minutes in $\frac{30}{8} 	imes 3 = \frac{90}{8} = 11.25$ hours,which is $11$ hours and $15$ minutes.Adding $11$ hours and $15$ minutes to $5$ pm on Tuesday gives $4:15$ am on Wednesday.

My watch was $3$ minutes slow at $5$ pm on Tuesday and it was $5$ minutes fast at $11$ pm on Wednesday. When did it give the correct time?
