Best answer
Correct Answer - Option 4 : 21% profit

Given:

cp = 11 article = Rs. 10

sp = 10 article = Rs. 11

Formula used:

SP = CP × (100+P %)/100

CP = SP × 100/(100 + p %)

Calculations:

                           Article                       price                

⇒      cp               11                            Rs. 10

⇒      sp               10                            Rs. 11                   

We will equate the quantity of article 

                          Article                       price                

⇒      cp            11 × 10                     Rs. 10 × 10

⇒      sp            10 × 11                     Rs. 11  × 11

⇒ cp = Rs. 100

⇒ sp = Rs. 121

⇒ Profit% = (121 - 100) × 100/100

⇒ Profit% = 21%

∴ The profit% is 21%.
