The age of father is 3 years more than 3 times the son’s age. 3 years hence, the age of the father will be 10 years more than twice the age of the son. The present age of father and son are respectively (in years)
a)	10, 33	b)	33, 9	c)	33, 10	d)	None of these

Let the present age of father be years and the present age of son be years.

∴ According to question, we have

                                                                                                            …(i)

Again, 3 years hence, age of father= years and that of son’s = (years.

∴ or                                                                                    …(ii)

Solving (i) and (ii), we get and

∴ Age of father=33 years and age of son=10years

Alternative Method:

Let son’s present age = years then father’s age = (3years

∴ (age of son)

Also, father’s present age is 3years.
