    C 315 Correct Answer Incorrect Answer
    D 320 Correct Answer Incorrect Answer
    E 330 Correct Answer Incorrect Answer

    Solution

    Ratio of profit share of A to B = [x + 45 + x + 45 + 70]:[x – 55 + x – 55 + 140] = [2x + 160]:[2x + 30] According to question; (2x + 160)/(2x + 30) = 6/5 => 10x + 800 = 12x + 180 => 2x = 620 => x = 310
