Verified Answer
The average age of a man and his son is 54 years. The ratio of their ...
Let their ages be 23x and 13x respectively.
The average age is 54 years which means the sum of their ages = 108 years.
i.e. 36x = 108
or x = 3
Hence their ages are 69 and 39 years, respectively.
After 6 years, their ages would be 75 and 45 years
So the required ratio = 75:45 = 5:3
