  1. Sir, with all due respect, I think the answer in item no. 6 is letter D. The answer key is letter B. Let me show my solution:

    Original Cost = 800 / 1.25 = 640
    Profit = 800 - 640 = 160
    Profit in % = 160 / 640 = 0.25 or 25%

    Where as if the profit is 200,

    Original Cost = 800 - 200 = 600
    Profit in % = 200 / 600 = 33.33%
