After replacing an old member by a new member,it was found that the average age of five members of a club is the same as it was $3$ years ago. The difference between the ages of the replaced and the new member is (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)?

The ratio of the present age of Manoj to that of Wasim is $3:11$. Wasim is $12 \text{ years}$ younger than Rehana. Rehana's age after $7 \text{ years}$ will be $85 \text{ years}$. What is the present age of Manoj's father,who is $25 \text{ years}$ older than Manoj? (in $\text{years}$)

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 $x$?

The age of the father $10 \,years$ ago was thrice the age of his son. Ten $years$ hence,father's age will be twice that of his son. The ratio of their present age is

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:
