Answer 1

Answer:

14.782

Step-by-step explanation:

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%.
