Question

    Determine the value of ‘p’ if p% of 600 + {1440 ÷ p of

    16} × 8 = 156
    A 25 Correct Answer Incorrect Answer
    B 18 Correct Answer Incorrect Answer
    C 10 Correct Answer Incorrect Answer
    D 6 Correct Answer Incorrect Answer

    Solution

    ATQ,

    p% of 600 + {1440 ÷ p of 16} × 8 = 156

    Or, 6p + 720/p = 156

    Or, p² – 26p + 120 = 0

    Or, p² – 20p – 6p + 120 = 0

    Or, p(p – 20) – 6(p – 20) = 0

    Or, (p – 6)(p – 20) = 0

    Or, p = 6 or p = 20
