    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
