 Age of ages (Posted on 2003-07-16)
Thanks to Ravi for introducing me to these with his problems but here goes. A father, mother, son, daughter and grandmother are all compairing ages. They find out this:

1) When the mother was the daughter' current age, the grandmother was twice as old as the father.

2) In one year, the father will be twice as old as his son.

3) When the daughter was 2/3 her current age, the son was twice as old as she was.

4)When the mother was 10 years younger than the daughter will be when she is twice her current age, the grandmother was twice as old as the mother was.

What are all the ages in the family?

if the son were 10 and the father 19, or the more realistic example of the son 20 and father 39, then next year the son would also be 1 year older, and 20 is not twice 11, and 40 is not twice 21. That is, 2 says that next year the father will be twice as old as the son is then, not as the son is now.
