You have the misfortune to own an unreliable clock.This one loses exactly 20 minutes every hour.It is now showing 8:00 a.m.and you know that it was correct at midnight,when you set it.The clock stopped 10 hours ago,what is the correct time now?
You have the misfortune to own an unreliable clock.This one
Solution:
The clock shows 8:00 am.
It means 8×60 = 480 min past by the clock.
The actual time past by normal clock = (480÷40)×60 = 720 min = 12hr
The time delayed is 12 - 8 = 4hr.
We also know the clock stopped 10 hours ago.
So,the correct present time = 8:00am + 4hr + 10hr = 10:00pm
Ans :It is 10:00pm now.
