One day Harry and I set our watches together. None of us was aware that my watch was getting faster by 2 min per hour and Harry’s watch was getting slower by 1 min per hour. After sometime, we discovered that my watch was 1 hr ahead of Harry’s watch. Can you find out after how long we noticed this ?

Your watch is gaining 2 minutes/hr, therefore it gains 2x minutes for x number of hrs.
And, Harry's watch is loosing 1 minutes / hr., so its loss of time is (- x) minutes for x hrs.
Given that, 2x-(- x) = 60
Hence, x = 20 hrs

ur watch's hour = 62 minuites
Harry's watch's hour = 59 minuites
after x hours...
ur watch will show 62x minuites
Harry's watch will show 59x minuites
62x - 59x = 60
3x = 60
x = 20 hours
