The cost price of 13 articles is equal to the selling price of 11 articles. Find the profit percent ?

A. 15 5/15%

B. 18 2/11 %

C. 6 2/3%

D. 30%

**Answer : **B. 18 2/11 %

## Explanation:

** Given : **

Cost Price = 13 and Selling Price = 11

According to the formula,

Profit % = ( (C.P - S.P / S.P) * 100 ) %

Profit % = ( (13 - 11 / 11) * 100 ) %

= ( (2 / 11) * 100 ) %

= 18 2/11 %
