Question

Q1.if the cost of the prices of a book 73% of the selling price what is the profit percent

​

Answer 1

Step-by-step explanation:

36.98%

Explanation:

Let the selling price of the book be x.

Then according to question, Cost Price of the book is 73% of selling price,

Cost Price = 73% of Selling Price

Cost Price = (73/100) × x

Cost Price = 73x/100

We know that,

Profit = Selling Price - Cost Price

= x - 73x/100

= (100x - 73x)/100

= 27x/100.

We know that,

$\begin{gathered}\text{Profit}\%=\frac{\text{Profit}\times100}{\text{Cost Price}}\\\;\\\text{Profit}\%=\frac{\frac{27x}{100}\times100}{\frac{73x}{100}}\\\;\\\text{Profit}\%=\frac{27}{73}\times100\\\;\\\text{Profit}\%=36.98\%\end{gathered}$
