Answer 7

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

Answer 8

3/2 slower means?

Answer 9

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 :-(

Answer 10

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

Answer 11

so i guess 6+2+4+12

Answer 12

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

Answer 13

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