Answer» 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 = 4/99 ( X + 8 ) = 4 ( X + 33 )9X + 72 = 4X + 1329X - 4X = 132 - 725X = 60X = 60/5X = 12 years.Present age of son = X = 12 Years.And,Present age of mother = X + 25 = 12 + 25 = 37 years. |
