a man is 30 years older than his son. in two years, his age will be twice the age of his son. the present age of this son is
divide(subtract(30, subtract(multiply(const_2, const_2), const_2)), subtract(const_2, const_1))
"explanation : let ' s son age is x , then father age is x + 30 . = > 2 ( x + 2 ) = ( x + 30 + 2 ) = > 2 x + 4 = x + 32 = > x = 28 years option a"
