A circle has a radius $$R$$ and a circumference $$l$$. If we increase the radius of this circle by 1 unit, then the ratio between the new circumference and the old circumference of this circle can be expressed as $$A + \dfrac B{CR }$$, where $$A,B$$ and $$C$$ are integers with $$B,C$$ coprime positive integers.

Submit your answer as $$A+B+C$$.
