I'm sorry i just couldn't miss it.

Not the answer you are looking for? Search for more explanations.
yea its option no.a
but dont know the process..
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
3/2 slower means?
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?
so i guess 6+2+4+12
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.
