Answer: Option A

Solution(By Examveda Team)

According to the question,
Cost price = 1200
Repair = 200
Total Cost price = Rs. 1400
Selling price = Rs. 1680
Profit = 280
$$\eqalign{ & {\text{Profit }}\% = \frac{{280}}{{1400}} \times 100 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 20\% \cr} $$
