    Question

    A Person 'P' bought 240

    earphones, which was 20% more than the number of speakers he bought. He sold each earphone at Rs. 20 for 8, and each speaker at Rs. 6. What % of the total earnings from selling both earphones and speakers came from the sales of the speakers alone?
    A 33.33% Correct Answer Incorrect Answer
    B 12.45% Correct Answer Incorrect Answer
    C 11.65% Correct Answer Incorrect Answer
    D 66.66% Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Number of speakers purchased by P = 240/1.2 = 200 Amount earned by selling all the Earphones = 240 × (20/8) = Rs. 600 Amount earned by him after selling all the speakers = 200 × 6 = Rs. 1200 Required % = {1200/(1200 + 600)} ×100 = 66.66%
