The ratio of the present ages of $Ram$ and $Rakesh$ is $6:11$. $4$ years ago,the ratio of their ages was $1:2$. What will be $Rakesh$'s age after $5$ years? (in years)

One $year$ ago,a father was four times as old as his son. In $6$ $years$ time,his age will exceed twice his son's age by $9$ $years$. The ratio of their present ages is:

Three times the present age of a father is equal to eight times the present age of his son. $8$ years hence,the father will be twice as old as his son at that time. What are their present ages?

The age of the father is $30 \text{ years}$ more than the son's age. Ten $\text{years}$ hence,the father's age will become three times the son's age at that time. What is the son's present age in $\text{years}$?

$A$ father is now $3$ times as old as his son. $5$ years back,he was $4$ times as old as his son. The age of the son is:

The ratio between the present age of Manisha and Deepali is $5:x$. Manisha is $9$ years younger than Parineeta. Parineeta's age after $9$ years will be $33$ years. The difference between Deepali's and Manisha's age is the same as the present age of Parineeta. What will come in place of $x$?
