GMAT Question of the day

A Clock loses exactly 24 minutes per hour. The Clock is now showing 3.00 A.M. If the clock was corrected a midnight and it stooped 1 hour ago, What is the correct time now.

1) 6 AM
2) 11 PM
3) 3 AM
4) 10 AM


Since clock loses 24 mins per hour
36 mins on clock = 1 hour actual
So
3 hours on clock = (60/36)*180 = 5 hrs actual

Since the clock was corrected at midnight its 5 AM and since it stopped one hour before it should be 6 AM
