Solution(By Apex Team)

$\begin{array}{l}\text{Sell sugar }\\ \text{= 950 g instead of 1000 g}\\ \text{Profit in sugar}\\ \text{= 1000-950 = 50 g}\\ \text{Now, % profit}\\ =\frac{50\times100}{950}=5\frac{5}{19}\%\\ \end{array}$ Short-cut $\begin{array}{l}\%\text{ profit }\\ =\frac{\text{ Goods left }}{\text{ Goods sold }}\times100\\ =\frac{50}{950}\times100\\ =5\frac{5}{19}\%\end{array}$
