Answer 1

Answer:

120 %

Step-by-step explanation:

Let CP = 100 x

% profit = 10% , CP = 100x

% profit = (SP - CP) * 100 / CP

If he sells at 10 % profit = 110 x

Certain Price or SP = 110 x

If it sold at Double the price, SP = 220 x

SP = 220 x, CP = 100 x

% profit = ( SP-CP)*100/CP

% profit = 120 %
