Sohan sells sugar at the cost price but uses false weights thus gaining 28% profit. How many grams of sugar is he giving for 3.2 kg sugar?

Sohan gains a 28% profit by using false weights.

The labeled weight of sugar is 3.2 kg.

​$$\text{Actual weight} = \frac{\text{Labeled weight}}{1 + \frac{\text{Profit Percentage}}{100}} ​$$​​

Substituting the values in the formula;

​$$\text{Actual weight} = \frac{3.2 \text{ kg}}{1 + \frac{28}{100}} \\ \ \\ = \frac{3.2}{1 + 0.28} \\ \ \\ = \frac{3.2}{1.28}= \\ \ \\ 2.5 \text{ kg}= \bf 2500 \text{ grams}$$​​

Thus, Sohan is giving 2500 grams of sugar for the labeled weight of 3.2 kg.
