      Question

      'A' varies directly as 'B'. If at 'A' = 25, value of 'B'

      is 40, then find the value of 'A' at 'B' = 96.
      A 53 Correct Answer Incorrect Answer
      B 56 Correct Answer Incorrect Answer
      C 55 Correct Answer Incorrect Answer
      D 60 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 96 = 60
