      Question

      The value of 'A' is directly proportional to the value

      of 'B'. When 'A' equals 25, 'B' is 40. Using this relationship, determine the value of 'A' when 'B' is 92.
      A 54.0 Correct Answer Incorrect Answer
      B 62.5 Correct Answer Incorrect Answer
      C 57.5 Correct Answer Incorrect Answer
      D 56.5 Correct Answer Incorrect Answer

      Solution

      ATQ; A = k X B {Where 'k' is some constant} So, 25 = k X 40 Or, k = (5/8) So, A = (5/8) X 92 = 57.5
