    Explanation:

    let the amounts invested be 4p, 5p and 3p

    Net profit = Total profit - Total loss

    = 10x5p/100 + 25x3p/200 - 20x4p/100

    = 0.875p - 0.8p

    = 0.075p

    Therefore, profit% = (Net profit/Total investment) x 100

    = 0.075 x 100/12 

    = 0.0625%

    Hence, option 1 is the correct answer.
