Find their present ages of son and father, Mathematics

When the son will be as old as the father today their ages will add up to 126 years. When the father was old as the son is today, their ages add upto 38 years.  Find their present ages.

Ans: let the son's present age be x

Father's age be y

Difference in age (y - x)

Of this difference is added to the present age of son, then son will be as old as the father now and at that time, the father's age will be [ y + (y - x)]

APQ:

[x + (y - x)] + [y (y - x)] = 126 [y + (x - y)] + [x + (x - y)] = 38

Solving we get the value of      x and y
