Let us assume the age of son and father as 3x and 5x years respectively
If father is 75 years old now. It means 5x=75 Years
x=15 years
Present age of son : 3x=45 years
Present age of father: 75 years
Present age of father is 42 years and that of his son is 14 years. Find the ratio of
(a) Present age of father to the present age of son.
(b) Age of the father to the age of son, when son was 12 years old.
(c) Age of father after 10 years to the age of son after 10 years.
(d) Age of father to the age of son when father was 30 years old.
