The age of a father is three times that of his son. After $5$ years,double the father's age will be five times the son's age. The present age of the father and son (in $years$) is:

If the present age of $X$ is half that of $Y$ and after $20$ years the age of $Y$ will be $1 \frac{1}{2}$ times that of $X$,what is the present age of $X$?

The age of a father is twice that of his elder son. Ten years hence,the age of the father will be $3$ times that of the younger son. If the difference of ages of two sons is $15 \text{ years}$,the age of the father is (in $\text{years}$)

The ratio of the ages of $Ram$ and $Rahim, 10$ years ago was $1:3$. The ratio of their ages $5$ years hence will be $2:3$. Then the ratio of their present ages is:

The ages of $Ram$ and $Shyam$ differ by $16 \, \text{years}$. $6 \, \text{years}$ ago,$Shyam$'s age was thrice that of $Ram$'s. Find their present ages (in $\text{years}$).

$A$ father is aged three times more than his son Ronit. After $8 \, \text{years}$,he would be two and a half times of Ronit's age. After further $8 \, \text{years}$,how many times would he be of Ronit's age?
