Correct Answer: 38 : 23
Solution : Let the age of man and son be $7x$ and $4x$ respectively. Average age = $\frac{7x+4x}{2}$ ⇒ $55= \frac{11x}{2}$ ⇒ $x= 10$ Age of man after 6 years = $7x+6$ = 76 Age of son after 6 years = $4x+6$ = 46 Required ratio = 76 : 46 = 38 : 23 Hence, the correct answer is 38 : 23.
