Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:

Answer: Option B

Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500
Selling Price (S.P.) = Rs. 5800
Gain = (S.P.) - (C.P.) = Rs. (5800 - 5500) = Rs. 300
$$\begin{array}{rl}& \text{Gain}\%\\ & =\left(\frac{300}{5500}\times 100\right)\%\\ & =5\frac{5}{11}\%\end{array}$$
