       Case I. Minute hand is 3 min. spaces behind the hour hand.


In this case, the minute hand has to gain' (25 - 3) = 22 minute spaces. 55 min. are gained in 60 min.


22 min. are gained in (60*22)/55min. = 24 min.


:. The hands will be 3 min. apart at 24 min. past 5.


     Case II. Minute hand is 3 min. spaces ahead of the hour hand.


In this case, the minute hand has to gain (25 + 3) = 28 minute spaces. 55 min. are gained in 60 min.
