    Question

    Find the fourth proportion of (2k - 5), (k + 1), and (3k +

    4). (Note: 'k' is the smallest two-digit prime number.)
    A 22 Correct Answer Incorrect Answer
    B 26 Correct Answer Incorrect Answer
    C 28 Correct Answer Incorrect Answer
    D 32 Correct Answer Incorrect Answer

    Solution

    k = 11 (smallest two-digit prime)
    2k - 5 = 22 - 5 = 17
    k + 1 = 11 + 1 = 12
    3k + 4 = 33 + 4 = 37
    17 : 12 :: 37 : m
    17m = 12 × 37 = 444
    m = 444 ÷ 17 = 26
