Question
I reached Arun’s birthday party 2 hours ago and I was 2 hours late to the party. The party started on time and lasted 3 hours ending at 10 pm. What is the time now?
Solution
To solve this problem, we need to work backwards from the end of the party.
- The party ended at 10 pm.
- The party lasted 3 hours, so it started at 10 pm - 3 hours = 7 pm.
- You were 2 hours late to the party, so you arrived at 7 pm + 2 hours = 9 pm.
- You reached the party 2 hours ago, so the current time is 9 pm + 2 hours = 11 pm.
So, the time now is 11 pm.
