Answer 2

Answer:

The profit of 4.5% is in the transition .

Step-by-step explanation:

Given as :

The percentage increase in price of the item = x = 10%

The percentage decrease in price of the item = y = 5 %

Let The profit or loss in this transaction = z %

According to question

The profit or loss in this transaction =  percentage increase in price of the item -  percentage decrease in sale of the item - $\dfrac{percentage increase \times percentage decrease}{100}$

Or, z = x - y - $\dfrac{x y}{100}$

Or, z = 10% - 5% - $\frac{10\times 5}{100}$

Or, z = 5% - 0.5

Or z = 4.5%

So, The percentage change in the transition = z = 4.5% profit

Hence, The profit of 4.5% is in the transition . Answer
