Share

Between 10 A.M. on Monday to 1:00 PM the following day, the watch gained 4.5 minutes. 

So, in 27 hours, the watch gained 4.5 minutes. 

It means, the watch gained every minute in every $$\dfrac{27}{4.5}=6$$ hours

At 10:00 AM, the watch was 2 minutes slow, so the watch would be showing accurate time in next 2*6 = 12 hours i.e. 10:00 P.M.
