$7$ 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)?

The present ages of Vishal and Shekhar are in the ratio of $14: 17$. $6 \, \text{years}$ from now,their ages will be in the ratio of $17: 20$. What is Shekhar's present age (in $\text{years}$)?

The ages of $A, B$ and $C$ together is $185$ years. $B$ is twice as old as $A$ and $C$ is $17$ years older than $A$. Then,the respective ages of $A, B$ and $C$ are (in years):

The ratio between the school ages of Neelam and Shaan is $5:6$. If the ratio between one-third of Neelam's age and half of Shaan's age is $5:9$,then what is the school age of Shaan (in years)?
