Question

loss= cost price______ answer math question​

Answer 1

Loss=Cost price-Selling price

Answer 2

Given,

• loss = cost price - ______

Direct answer -

• Loss = Cost price (CP) - Selling price (SP)

This formula is used when the CP of an article is more than its SP. It indicates a loss for the seller.

To find the loss percentage, we use -

$\sf{{loss \: \% \: = \: \frac{loss}{CP} }{ \: \times \: 100 }}$

Example -

Let's take the example of a sum and solve it with the above formula for better understanding.

✇ Tabu bought a pencil box for ₹25 and sold it for ₹21. Find her loss and loss percentage.

→ As we know,

Loss = CP - SP

We get,

₹25 - ₹21 = ₹4

∴ Tabu had a loss of ₹4.

Now, We know that :

$\sf{{⟹ \: loss \: percentage\: = }{ \: \frac{loss}{CP} \times 100}}$

As per question,

$\sf{{⟼ \: \frac{4}{25} \: \times \:100 }{ \: = 16 }}$

∴ The loss percentage is 16%.

Remember these -

• Profit = SP - CP.
• $\sf{{Profit \: percentage\: = \: \frac{profit}{CP} }{ \times 100\: }}$
• If there is a profit of r% then

$\sf{{⟼ \: \: \: \: SP \: = (1 + \frac{r}{100})CP \: }{ \: }}$

• If there is a loss of r% then

$\sf{{⟼ \: \: \: \: SP\: = (1 - \frac{r}{100})CP }{ \: }}$
