Question

A man buys a radio set for 900 and sells it for 972. What is his profit or loss per cent?​

Answer 1

Given,

Cost price of a radio is $900$

Selling price of that radio is $972$

Profit gained by that person is

$Profit=Selling price-Cost price$

$=972-900\\=72$

Formula for profit percentage:

$Profit percentage=\frac{Profit}{Cost price} \times100$

$=\frac{72}{900} \times100$

$=8$%

Therefore profit percentage is $8%$%

Answer 2

Answer:

$8$%

Step-by-step explanation:

As per the given data,

Cost price of the radio set $=900$

Selling price of the radio set  $=972$

We know,

Profit = Selling price - cost price

$\Rightarrow Profit= 972-900=72$

Profit% $=\frac{Profit}{cost price}\times100$

$=\frac{72}{900}\times100=8$

Hence, his profit percentage is $8$%
