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?

(In reply to re: Solution by Viet)

Actually Charlie is right - the wording of the statement must be considered carefully. It doesn't say:

"In one year, the father will be twice as old as the son is NOW"

Think of the statement as saying "Let one year of time pass. At that point the father will be twice as old as his son."

Does that help, Viet?

Later!
