    A 70 Correct Answer Incorrect Answer
    B 210 Correct Answer Incorrect Answer
    C 140 Correct Answer Incorrect Answer
    D 280 Correct Answer Incorrect Answer

    Solution

    Let the number = n Then, 28% of n + 82% of n = 125% of 484 110% of n = 5/4 * 484 11n/10 = 605 n = 550 When 150 is subtracted from the number, then resultant = 550 - 150 = 400 Therefore, 35% of 400 = 140
