There are $$10$$ sevens in the unit digit, $$10$$ seventys, $$9$$ fives in the units (as fifteen is not fiveteen) plus eleven and twelve. 
If I write all the whole numbers from $$1$$ to $$100$$ in words, how many times will I write the letter V? 
(a) $$19$$ 
(b) $$29$$ 
(c) $$30$$ 
(d) $$31$$ 
(e) $$32$$
