Answer:
B
Explanation:
Profit/gains on car = Selling Price - Buying price = 10000 - 2000 = $8000
Profit/gains on motorcycle = SP - BP = 800 - 1000 = $ - 200 (because it's negative, its actually not a gain but a loss, so the loss on motorcycle = $ 200 and profit/gains will be negative)
Total gains = 8000 - 200 = $7800
