Question

A clock which gains 5 minutes every 12 hours is set right at 5 AM. What will be the real time, when the clock shows 5 PM after 5 days ?

Answer 1

Answer:

4:05 pm

Explanation:

As we will reduce around 5 min every day taken in account about AM and PM we will loose around 55 min so it will show 4:05 PM.

Answer 2

The real-time, when the clock shows 5 PM after 5 days will be 4:05 PM.

It is given that the clock gains 5 minutes every 12 hours. It is set right at 5 AM.

So In one day, we have 24 hours, therefore, the clock gains 10 minutes in one day. In 5 days it will gain 50 minutes.

Now the clock was set right at 5 AM therefore till 5 PM 12 more hours will be passed and the clock will gain 5 more minutes.

Therefore a 5 PM after 5 days the clock will have gained 55 minutes.

So the original time will be 55 minutes less than 5 PM i.e. 4:05 PM.
