Given, Present age of father = 42years and that of his son =  14 years.

The ratio of

               (a) Present age of father to the present age of the son:

                              =\frac{42}{14}=\frac{3}{1}=3:1

                 

               (b) Age of the father to the age of the son, when the son was 12 years old: 

                             =\frac{42-2}{14-2}=\frac{40}{12}=\frac{10}{3}=10:3

               (c) Age of father after 10  years to the age of son after 10 years:

                                =\frac{42+10}{14+10}=\frac{52}{24}=\frac{13}{6}=13:6.                                   

               (d) Age of father to the age of son when father was 30  years old.

                                  =\frac{42-12}{14-12}=\frac{30}{2}=\frac{15}{1}=15:1
