(related to Problem: Mamma's Age)

The age of Mamma must have been $29$ years $2$ months; that of Papa, $35$ years; and that of the child, Tommy, $5$ years $10$ months. Added together, these make seventy years. The father is six times the age of the son, and, after $23$ years $4$ months have elapsed, their united ages will amount to $140$ years, and Tommy will be just half the age of his father.
