    The total of three numbers, A, B, and C, is 2450. The

    second number, B, is 4/7 greater than the first number, A. The third number, C, exceeds A by 375. Determine the value of A.
    A 581 Correct Answer Incorrect Answer
    B 254 Correct Answer Incorrect Answer
    C 752 Correct Answer Incorrect Answer
    D 355 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    Let A = x

    Then B = x + (4/7)x = 11x/7

    C = x + 375

    Sum: x + (11x/7) + (x + 375) = 2450

    Multiplying by 7: 7x + 11x + 7x + 2625 = 17150

    25x = 14525

    x = 581
