    Question

    If P:Q:R = 2:3:5 and R – P = 72, then what is the value

    of 3P + 2R – Q?
    A 175 Correct Answer Incorrect Answer
    B 159 Correct Answer Incorrect Answer
    C 115 Correct Answer Incorrect Answer
    D 192 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let P = ‘x’

    then, Q = x × (3/2) = ‘1.5x’

    And, R = x × (5/2) = ‘2.5x’

    ATQ;

    2.5x – x = 72

    Or, 1.5x = 72

    So, x = 48

    So, ‘P’ = 48, ‘Q’ = 1.5 × 48 = 72 and ‘R’ = 2.5 × 48 = 120

    Required value = (3 × 48) + (2 × 120) – (72) = 192
