    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Ratio of profit received by ‘V’ and ‘W’ = {5400 × (u + 7)}:{6200 × (u - 2)} = (8700 – 3300)/3300 Or, (5400u + 37800):(6200u - 12400) = 5400/3300 Or, (18u + 126):(20.67u - 41.33) = 9/5.5 Or, 99u + 693 = 113.685u - 226.315 Or, 919.315 = 14.685u Or, u = 919.315/14.685 = 62.6 (approximately 63)
