Answer is Gain of 20% Explanation: Loss = 40% SP (selling price) = Rs. 40 Calculating Cost price from Selling Price: $$\frac{SP}{100 - Loss}\text{%} = CP$$ $\therefore CP = \frac{40}{60}\times100 = \text{Rs. }\frac{200}{3}$ $\text{When SP = Rs. 80}$ $Profit = 80 - \frac{200}{3} = \text{Rs.}\frac{40}{3}$ $\therefore \text{Gain %}= \frac{\frac{40}{3}}{\frac{200}{3}}\times100= \text{20 %}$ praksha ? answered Jul 1 '2017 at 21:41 All Comments
