Show Answer
Answer:
Correct Answer: D
Solution:
- Let S.P. of the Scooter be $ Rs.x $
$ \therefore $ C.P. of the Scooter $ =Rs.\frac{13x}{15} $ and S.P. of the Scooter $ =Rs.\frac{112\times x}{100} $
$ \therefore $ Gain $ %=( \frac{12x}{100}-\frac{13x}{15} )\times \frac{100\times 5}{13x}% $ $ =\frac{336x-260x}{300}\times \frac{1500}{13x}%=29\frac{3}{13}% $
