### Solution:

Concept:Create a linear equation with two variables based on the given data and solve them to find the current age of the father and son. We have some relationships regarding the age of father and son. You need to find her exact current age. Find her current age by creating linear equations with two variables and solving them. Let's assume the boy's current age isYear and current age of father is Year.

Given,

Sum of ages of a father and his son years

Five years ago, product of their ages years

Let,

Present age of father years

Present age of son years

Now, forming a quadratic equation,

Clearly, cannot be 9 the age of father cannot be less than his son's age.

Present age of father, years

and, present age of son, years

Therefore, the father's current age is and the son is Hence, the correct answer is option 1 and 3.
