A) 45 year and 15 year  B) 40 year and 10 year  C) 42 year and 12 year  D) 41 year and 11 year  E) None of these
Let my age is x years and my son’s age is y years, Then,   x = 3y   Five years later, my age will be (x + 5) years and my son’s age will be   (y + 5) years   Thus, (x + 5) = 5/2 (y + 5)   =&gt; 2x - 5 y - 15 =0   putting x = 3y, we get   6y - 5y - 15 = 0   =&gt; y = 15   Thus, x = 45   Hence, my present age is 45 years and my son’s present age is 15 years.   45 year and 15 yearNSWER:45 year and 15 year
