The ratio of the father's age to the son's age is 3: 1. The product of their ages is 147. The ratio of their ages after 5 years will be?

Let the son's age = x. therefore, the father's age be 3x, Given the product of their ages = 147. => x * 3x = 147 => 3x² = 147. => x² = (147/3) => x² = 49 => x = 7. Therefore, present age of son = x = 7 years. Present age of father = 3x = 21. Age of father after 5 years = 21+5 = 26 years. Age of son after 5 years = 7+5 = 12 years. Ratio=13 : 6
