Ancient Coin Puzzle

Ancient Coin!!
A thief went to a shop that sold antique coins. He stole a coin from Emperor Alexander’s time that had 326 B.C. inscribed on it. These rare coins were worth $ 100 for every year of their age (years from date of minting till now). So how much did the thief get for his stolen coin?

Vacation Time

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?

Up an Escalator

Jimmy takes the underground train to work and uses an escalator at the railway station. If Jimmy runs up 7 steps of the escalator, then it takes him 28.5 seconds to reach the top of the escalator. If he runs up 13 steps of the escalator, then it takes him only 19.5 seconds to reach the top.

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