Age of a father and his son is in the ratio of 5 : 2. After two years, the ratio becomes 19 : 8. What are the present ages of father and son respectively ?
Choose the correct choice from the following choices:
A) 45 and 12  B) 35 and 12  C) 40 and 16  D) 45 and 18  E) 55 and 22
Let present ages of father and son be 5x : 2x.   After two years:   (5x + 2) / (2x + 2) = 19 / 8   40x + 16 = 38x + 38 =&gt; 2x = 22 =&gt; x = 11.   Father = 5x = 5 x 11 = 55; Son = 2x = 2 x 11 = 22   Option 55 and 22
