Question

A clock gains 5 minutes every hour and was set right at 6:00 PM on Friday. When does it shows the right time again? 
1. 6:00 AM on Friday
2. 6:00 PM o Friday
3. 6:00 AM on Thursday
4. 6:00 PM on Thursday
5. None of the above

Answer 1

Correct Answer - Option 4 : 6:00 PM on Thursday

5 minutes gained in 1 hour.

So, 1 hour gained in 12 hours.

And 12 hours gained in 144 hour = 6 days.

After gaining 12 hours, it is the same time that appear.

So, after 6 days the same time occurs. Which is 6:00 PM on Thursday.

Hence 6:00 PM on Thursday is the correct answer.
