    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?

    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 + 600)/1200} ×100 = 150%
