112%
233¹/₃%
320%
422%

Answer:- 1

Explanation:-

Solution:

Cost price of 28 articles = Selling price of 21 articles

\frac{CP}{SP} = \frac{21}{28} = \frac{3}{4}

$\frac{{{\text{CP}}}}{{{\text{SP}}}} = \frac{{21}}{{28}} = \frac{3}{4}$ Profit = Selling price - Cost price = 4 - 3 = 1

\begin{aligned} Profit % = \frac{1}{3} \times 100 \\ = 33 \frac{1}{3} % \end{aligned}

$\eqalign{ & {\text{Profit }}\% = \frac{1}{3} \times 100 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 33\frac{1}{3}\% \cr}$
