    Step-by-step explanation:

    Let original cost =100

    so original SP=110

    New CP = 110

    New SP=132

    Profit=22

    profit %=22/110*100=20%

    Answer:

    14.782%

    Initially as profit was 10% so SP1 = 11/10 CP1

    Final as profit is 15% so SP2 = 23/20 CP2.

    Now SP2 is 120% of SP1 so SP2/SP1 = 5/6.

    Now putting all variables in game.

    5/6 = (11/10) CP1/ (23/20) CP2, from here CP2/ CP1 = 132/115 so change is 17/115 that is 14.782%.
