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:

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 $X$?

Ram's present age is three times his son's present age and $\frac{2}{5}$ of his father's present age. The average of the present ages of all of them is $46 \, \text{years}$. What is the difference between the Ram's son's present age and Ram's father's present age? (in $\text{years}$)

$A$ father's age is three times the sum of the ages of his two children,but $20 \, \text{years}$ hence his age will be equal to the sum of their ages. Then,the father's age is (in $\text{years}$)

The ratio between the present ages of $P$ and $Q$ is $6:7$. If $Q$ is $4 \text{ years}$ older than $P$,what will be the ratio of the ages of $P$ and $Q$ after $4 \text{ years}$?

The sum of the ages of $4$ members of a family,$5$ $years$ ago,was $94$ $years$. Today,when the daughter has been married off and replaced by a daughter-in-law,the sum of their ages is $92$ $years$. Assuming that there has been no other change in the family structure and all the people are alive,what is the difference between the age of the daughter and that of the daughter-in-law? (in $years$)
