Answer 2

Answer :-

• The loss is Rs 20 and the loss percentage is 5%.

To find :-

• The loss and loss percentage.

Step-by-step explanation :-

• Before finding the loss percentage, let's find Ramen's loss!

We know that :-

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

Where,

• CP = Cost price.
• SP = Selling price.

Here,

• Cost price = Rs 400.
• Selling price = Rs 380.

Therefore,

$\longrightarrow \bf Loss = 400 - 380$

$\longrightarrow \bf Loss = Rs \: 20$

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

• Now as we know the loss, let's find the loss percentage!

We know that :-

$\underline{\boxed{\sf Loss \: \% = \dfrac{Loss}{CP} \times 100}}$

Where,

• CP = Cost price.

Here,

• Loss = Rs 20.
• Cost price = Rs 400.

Therefore,

$\dashrightarrow\:\tt Loss \: \% = \dfrac{20}{4\!\!\!\not0\!\!\!\not0} \times 1\!\!\!\not0\!\!\!\not0$

$\dashrightarrow \: \tt Loss \: \% = \cancel{\dfrac{20}{4}} \times 1$

$\dashrightarrow \: \tt Loss \: \% = \dfrac{5}{1} \times 1$

$\dashrightarrow \: \tt Loss \: \% = 5\%$

Hence :-

• The loss = Rs 20.
• The loss percentage = 5%.
