Count your steps
Oh, how I wish I were young again!
This wish to be young again took hold of me when I saw my neighbour's 12-year-old son leaping up the stairs two at a time. Now, I could not do that.
Well, I was walking down taking one step at a time. I had walked down seven steps when I saw the boy start from the bottom, and make a rush for the top.
I continued walking down in my slow one-step pace. The boy, on the other hand, climbed two steps at a time; he was an energetic little fellow.
There were still four steps left for me to walk down when I saw that the boy had already reached the top.
It is then that I let out a sigh and wished I were young again. It suddenly occurred to me that I had never counted the number of steps the staircase had. I did not want to climb up the stairs there and then (you know the reason!) to count the number of steps. But from the information that I have provided, can you help me find out the number of steps.
I will repeat the essential details:
1. I had walked down seven steps when the boy started from the bottom.
2. I had yet to walk down four steps to reach the bottom when the boy had already reached the top.
3. The boy had climbed two steps at a time throughout.
