Answer:
Option A
Explanation:
Amount to buy 20 Advanced PCs in USA = 20 x 2000 = 40000
Amount to sell 20 Advanced PCs in India = 20 x 2600 = 52000
Profit Gained = Selling price - Cost price = 52000 - 40000 = 12000
profit Percentage = $\frac{profit}{Cost Price}\times 100=\frac{12000}{40000}\times 100=30$
