Question

    If (p + 15)% of 240 is 30 more than the p% of 300, then

    find the value of 20% of (p + 10.5).
    A 4.1 Correct Answer Incorrect Answer
    B 5.2 Correct Answer Incorrect Answer
    C 3.3 Correct Answer Incorrect Answer
    D 7.5 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    [{(p + 15)/100} × 240] – {(p/100) × 300} = 30
    Or, 240p + 3600 – 300p = 3000
    Or, 60p = 600
    Or, p = 10
    Now,
    0.20 × (p + 10.5)
    = 0.20 × (10 + 10.5)
    = 4.1
