Answers
Let,
the Present age of the Son = x years
the Present age of the Father = y years
Acocording to the Conditions,
y - 10 = 12 ( x - 10) → 12x - y = 110...............1)
y + 10 = 2 ( x + 10 ) → 2x - y = -10 ................2)
Subtracting 2) from 1), we get
x = 12
Substituting the value of x = 12 in equation 2), we get
y = 34
Therefore the Present age of Son and Father is 12 years and 34 years respectively.
