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?
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.
