The milkman adds $$(frac{1}{5})^{th}$$ of water, thus total mixture = $$1+frac{1}{5} = frac{6}{5}$$ Cost price per litre of the mixture = $$frac{25}{frac{6}{5}} = 25 imes frac{5}{6} = Rs$$ $$20.83$$ Selling price per litre = Rs. 29 $$ herefore$$ Profit % = $$frac{29-20.83}{20.83} imes 100$$ = $$frac{817}{20.83} approx 39.2\%$$ => Ans - (B)
