The sum of father’s age and twice the age of his son is 70. If we double the age of the father and add it to the age of his son the sum is 95. Find their present ages.

Suppose father’s age(in years) be x and that son’s age be y.


Then,


…(I)


…(II)


Multiply Eq.I by 2 and equate





Substituting y=15 in Eq.II
