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?

Raman's present age is three times his daughter's and $9/13$ of his mother's present age. The sum of the present ages of all three of them is $125 \text{ years}$. What is the difference between the present ages of Raman's daughter and Raman's mother? (in $\text{years}$)

$A$ man's age is $125 \%$ of what it was $10 \, \text{years}$ ago, but $83 \frac{1}{3} \%$ of what it will be after $10 \, \text{years}$. What is his present age? (in $\text{years}$)

$7$ years ago,the ages (in years) of $A$ and $B$ were in the ratio $4:5$; and $7$ years hence they will be in the ratio $5:6$. The present age of $B$ is (in years):

The ratio of $A$'s and $B$'s ages is $4:5.$ If the difference between the present age of $A$ and $B$'s age $5$ years hence is $3,$ then what is the sum of the present ages of $A$ and $B$ (in years)?
