Question

a shopkeeper sells his goods at 80% of their cost price. Find his gain or loss percent

Answer 1

So let the CP of the goods be ₹100(for convenience)
So as per question, he sells them for 80% of CP, that is:
80/100 ×100= 80(100 divided by 100 is 1)
So SP = ₹80
SP is less than CP. So it's a loss.
Loss= ₹100- ₹80= ₹20
Loss percentage= (Loss/CP) ×100
(20/100) × 100 =20% loss (as 100 divided by 100 is 1& 1×20=20)
Therefore the shopkeeper occured a loss of 20%.

Answer 2

Loss% is 20%.

Step-by-step explanation:

Since we have given that

Selling price at 80% of cost price.

Let the cost price be x

Selling price be $\dfrac{80}{100}x=0.8x$

Since, Selling price < cost price.

So, Loss = cost price - Selling price

Loss = x - 0.8x

Loss = 0.2x

So, Loss% would be

$\dfrac{0.2x}{x}\times 100\\\\=0.2\times 100\\\\=20\%$

Hence, loss% is 20%.
