Answer 2

since age of Rajeev is one-third of his father
or we can say rajeev' s father is having thrice age as RajeevLet present age be x years.
Let present age of Rajeev' s father be = 3x yrs. rajeev age age after 12 years. = x +12 years
age of Rajeev' s father after 12 years= 3 x +12 years
according to the given situation,
3x + 12 =2( x +12)
3x + 12 =2x +24
3x - 2x = 24 -12
x =12years
present age of Rajeev =12 years
present age of Rajeev' s father =36 years
