Today is my birthday and the birthday of my granddaughter Imogen. My age today is a whole-number multiple of hers, and this has been true on one third of our joint anniversaries.
If we both live until I am six times her current age, then my age will be a multiple of hers on two more birthdays.
How old are we today?
