Expert Answer
Let the present age of the father be x years and present age of son be y years
Two year ago the age of father = x-2 years
Two year ago the age of son = y-2 year
Case I: x-2 = 5(y-2)
x-2 = 5y-10
x-5y = -8
5y-x = 8
5y-8 = x
Case II: x+2 =3(y+2) +8
Putting the value of y
5y-8+2=3y+6+8
2y = 20y = 10 years
Putting the value of y in equation 1
X = 5(10)-8 = 42years
Present age of father =42 years
Son's present age = 10 years
