On Selling a watch at $$\frac{4}{5}$$ of the marked price there is loss of 4%. What will be the ratio of the marked price and cost price of the watch?
Let marked price of the book = Rs. $$50x$$
=> Selling price = $$\frac{4}{5}\times50x=Rs.$$ $$40x$$
Loss % = 4%
=> Cost price = $$\frac{40x}{(100-4)}\times100=Rs.$$ $$\frac{125x}{3}$$
$$\therefore$$ Ratio of marked price and cost price of the book = $$\frac{50x}{\frac{125x}{3}}$$
= $$(50\times3):125=6:5$$
=> Ans - (A)
