A clock loses 4 minutes in one hour and set right at 4 PM. What will be the right time if the clock shows 8:40 PM? 

A clock loses 4 minutes in one hour and set right at 4 PM. What will be the right time if the clock shows 8:40 PM?  Correct Answer 9:00 PM

The faulty clocks show 4:56 at 5PM since it loses 4 minutes per hour.

And so, it loses 20 minutes in 5 hours. So, after 5 hours, the clock shows 8:40 PM instead of 9:00 PM.

So, the right time is 9:00 PM.

Hence,9:00 PM is the correct answer.
