By selling a fan for 600, a man loses 10%. To make a gain of 20%, the selling price of the fan should be
Selling price of fan = Rs. 600
Loss % = 10%
=> Cost price = $$\frac{600}{(100-10)}\times100$$
= $$\frac{6000}{9}=Rs.$$ $$\frac{2000}{3}$$
Profit % = 20%
$$\therefore$$ Selling price = $$\frac{2000}{3}+(\frac{20}{100}\times\frac{2000}{3})$$
= $$\frac{2000}{3}+\frac{400}{3}=\frac{2400}{3}=Rs.$$ $$800$$
