Question: A mother is 21 years older than her child. In 6 years the mother will be 5 times older than her baby.
Where is the father?
Answer: He is with the mother.
If you do the math: (baby's age) + 21 + 6 = 5 * (baby's age + 6)
(baby's age) + 27 = 30 + 5 * (baby's age)
-3 = 4 * (baby's age)
-3/4 = baby's age
The baby will be born in 9 months.
