      Question

      If P represents the largest single-digit prime number,

      determine the fourth proportional to the numbers (P + 3), (P - 2), and (P + 5).
      A 6 Correct Answer Incorrect Answer
      B 9 Correct Answer Incorrect Answer
      C 5 Correct Answer Incorrect Answer
      D 8 Correct Answer Incorrect Answer

      Solution

      'P' = 7

      So, the numbers are 10, 5 and 12.

      Let fourth proportion be 'm'.

      So, 10m = 5 X 12

      Or, 10m = 60

      Or, 'm' = 6
