Answer is : 12 Explanation : Let the original price be x Rs. $=\frac{80}{100} \times x = \frac{4x}{5} Rs$ $SP = \frac{4x}{5} \times \frac{140}{100} = \frac{28x}{25} Rs$ Gain on original price $\frac{28x}{25} - x =\frac{3x}{25}$ $\therefore \text{Gain % =}\frac{3x}{\frac{25}{x} \times 100} \text{= 12%}$ =12%   Nithin K ? answered Apr 3 '2018 at 20:1 All Comments
