    Ok, I'll try to explain This watch is 3/2 times slower then it should be, so in order to find out how much time passed when they worked you should multiply 6 by 3/2 (which is 9). 12 noon + 9h + 4h = 1 am

    This watch shows that 2/3 of an hour passes while it's really passes 1 hour. So you multiply 6 by 3/2 to compensate this. Dont know any better way to explain this :-(

    20 mins loss means in total 20*6 mins loss i.e.2 hr...isnt it?

    It's wrong to multiply by 6 because it is not really 6 hours passed (since the watch doesnt work properly)

    Watch worked for x hours, then x=6+x*20mins, where x*20 is the total loss.
