In the original story, the reference made by the mother
to the respective ages of her daughters is:

	"mother:   OK, you're right, I made it tough on you, but I have to go
	now and drive my oldest daughter to her piano lesson."

If the ages of the daughters are 1, 2, and 10, she has an oldest
daughter. The various solvers seem to have made the 
assumption that the other two daughters are the same age.

I did, by refraining from making an unwarranted assumption.
