Question

Mother is 25 year older than her son. Find son's age if after 8 years ratio of son's age to mother's age will be `4/9`.

Solution

Let the present age of the son be x years.
Age of the mother = (x + 25) years
After 8 years,
Age of son = (x + 8) years
Age of mother = (x + 25+ 8) years
                        = (x + 33) years
From the given information,

`("x" + 8)/("x" + 33) = 4/9`

⇒ 9 (x + 8) = 4 (x + 33)

⇒ 9x + 72 = 4x + 132

⇒ 9x - 4x = 132 - 72

⇒ 5x = 60

⇒ x = 12

Hence, the present age of the son is 12 years.

  Is there an error in this question or solution?
