Question

cost price = 300
selling price = 345
profit percent -
​

Answer 1

Answer :-

• The profit percent is 15%

Given :-

• Cost price = Rs 300.
• Selling price = Rs 345.

To find :-

• The profit percent.

Step-by-step explanation :-

• Before finding the profit percent, let's find the profit!

We know that :-

$\underline{\boxed{\sf Profit = SP - CP}}$

Here,

• Cost price = Rs 300.
• Selling price = Rs 345.

Hence,

$\boxed{\bf Profit = 345 - 300}$

$\overline{\boxed{\bf Profit = Rs \: 45}}$

-------------------------

• Now, as we know the profit, let's find the profit percent!

We know that :-

$\underline{\boxed{\sf Profit \: \% = \dfrac{Profit}{Cost \: Price} \times 100}}$

Here,

• Profit = Rs 45.
• Cost price = Rs 300.

Hence,

$\tt Profit \: \%= \dfrac{45}{300} \times 100$

Cutting off the zeroes,

$\tt Profit\:\% = \dfrac{45}{3} \times 1$

Reducing the numbers,

$\tt Profit\:\% = \dfrac{15}{1} \times 1$

Now let's multiply the remaining numbers since we can't reduce them anymore.

$\tt Profit \: \% = 15 \times 1$

Multiplying the numbers,

$\overline{\boxed{\tt Profit\: \% = 15\%}}$

Abbreviations used :-

CP - Cost Price.

SP - Selling Price.
