      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.

      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
