Step-by-step explanation:
Let present age of son be X years.
Age of mother = ( X + 25 ) years.
After 8 years age of son= ( X + 8 ) years.
After 8 years age of mother = ( X + 25 + 8 ) = ( X + 33 ) years.
According to the question,
=> X+ 8 / X + 33 = 4/9
=> 9 ( X + 8 ) = 4 ( X + 33 )
=> 9X + 72 = 4X + 132
=> 9X - 4X = 132 - 72
=> 5X = 60
=> X = 60/5
=> X = 12 years.
=> Present age of son = X = 12 Years.
=> Present age of mother = X + 25 = 12 + 25 = 37 years.
