Answer» Correct Answer - Option 4 : 11 ∶ 3 Given: The ages ratio of father and child = 9: 1 Their ages sum = 40 Calculations: Let the ages of the father and child be 9x and x According to the questions, ⇒ 9x + x = 40 ⇒ 10x = 40 ⇒ x = 4 The Ages of the father and the child are 36 years and 4 years The Ages of the father and the child 8 years later are 44 years and 12 years The required ratio = 44 ∶ 12 = 11 ∶ 3 ∴ The required ratio is 11 ∶ 3 |
