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%
