Eighteen $years$ ago,the ratio of $A$'s age to $B$'s age was $8: 13$. Their present ages are in the ratio $5: 7$. What is the present age of $A$ (in $years$)?

$5 \, \text{years}$ ago, Mr. Sohanlal was thrice as old as his son, and $10 \, \text{years}$ hence, he will be twice as old as his son. Mr. Sohanlal's present age (in $\text{years}$) is:

$Q$ is as much younger than $R$ as he is older than $T.$ If the sum of the ages of $R$ and $T$ is $60 \text{ years},$ what is definitely the difference between $R$ and $Q$'s age? (in $\text{years}$)

If twice the son's age be added to the father's age,the sum is $70 \text{ years}$ and if twice the father's age is added to the son's age,the sum is $95 \text{ years}$. Then the father's age is (in $\text{years}$):

The ratio between the ages of a father and a son at present is $5:2$. $4$ years hence,the ratio between the ages of the son and his mother will be $1:2$. What is the ratio between the present ages of the father and the mother?
