### No Sunrise Lateral Thinking Puzzle

No Sunrise Lateral Thinking Puzzle

In the middle of the night a man gets out of bed, walks to the yard and puts something in a bag. He then gets in his car, drives across town to his friend's house and rings the doorbell. His friend answers and the man says, "Here, you wanted it, so its yours." The man then smiles and drives home. As a result of all this, though, he never sees another sunrise in his life (but yes, he is alive).
How can you explain this? Now think laterally don't go by all what is given!!

### The City Population Puzzle

The City Population Puzzle
A mythical city contains 100,000 married couples but no children.
Each family wishes to “continue the male line”, but they do not wish to over-populate.
So, each family has one baby per annum until the arrival of the first boy.
For example, if (at some future date) a family has five children, then it must be either that they are all girls, and another child is planned, or that there are four girls and one boy, and no more children are planned.
Assume that children are equally likely to be born male or female. Let p be the percentage of children that are male at the end of year y.
How is this percentage expected to evolve through time?
