4 times in a Week
6 times in a Day

The first four letters are me.

Exterminates king, collapse town,
And blows the mountains down.

How old is your son? asked a man to his neighbour. My son is five times as old as my daughter and my wife is five times as old as my son. I am twice as old as my wife whereas my grandmother, who is celebrating her eighty-first birthday is as old as all of us put together.

What can run but never walks, has a mouth but never talks, has a head but never weeps, has a bed but never sleeps?
