    If 40% of 'P' is equal to 125% of 20% of 'Q', then find the

    ratio of 3P : Q.
    A 15:8 Correct Answer Incorrect Answer
    B 20:21 Correct Answer Incorrect Answer
    C 12:3 Correct Answer Incorrect Answer
    D 9:5 Correct Answer Incorrect Answer

    Solution

    ATQ,

    We have,

    ⇒ P × 0.40 = 1.25 × 0.20 × Q

    ⇒ 0.40P = 0.25Q

    ⇒ P : Q = 0.25 : 0.40 = 25 : 40 = 5 : 8

    ⇒ 3P : Q = 3 × 5 : 8 = 15 : 8
