Vacation Time

admin — Wed, 23 Sep 2009 09:43:07 +0000

It was vacation time, and so I decided to visit my cousin's home. In the mornings, we both would go for a jog. The evenings were spent on the tennis court. Tiring as these activities were, we could manage only one per day, i.e., either we went for a jog or played tennis each day. There were days when we felt lazy and stayed home all day long.

Now, there were 9 mornings when we did nothing, 13 evenings when we stayed at home, and a total of 12 days when we jogged or played tennis. For how many days did I stay at my cousin's place?

How many seconds would it take Jimmy to reach the top if he did not run up any steps of the escalator at all?
