    Let father's age be x and the sum of sons' ages be y. Therefore, x = 3y OR, x - 3y = 0 (1). Now, 5 years later, father's age = (x + 5) years. Sum of sons' ages = (y + 5 + 5) = (y + 10) years. Therfore, x + 5 = 2 (y + 10). x + 5 = 2y + 20. x - 2y = 15 (2). Solving (1) and (2), x = 45 and y = 15. Therefore, father's age = 45 years//
