    Answer: (3) 37.5 %

    Explanation:-
    The selling price of an item = Rs.640
    Loss = 20 %

    Then, the cost price of an item = 640 x 100/80
    = Rs.800

    If, hr makes profit 10 %,
    Then, the selling  price of an item = 800 x 110/100
    = Rs.880
    Increased the selling price = 880 – 640
    = Rs.240

    Percentage of increase  selling price = 240  x 100/640
    = 24 x 100 /64
    = 3 x 100/8
    = 3 x 25 /2
    =  37.5 %

    Hence, the answer is (3) 37.5%.
