Answer 1

Given :-

• Selling price of article = Rs. 80
• Loss percentage = 20 %

To Find :-

• Cost price of article

Solution :-

$\underline{\bf{\dag} \:\mathfrak{As\;we\;know\: that\: :}}$

$\star\: \boxed{\sf{\blue{CP = \dfrac{100 \times SP}{100 - Loss \%} }}}$

Where ,

CP = Cost Price

SP = Selling Price

→ Let's put the values in the formula

$\sf \implies \dfrac{80 \times 100 }{100-20}$

$\sf \implies \dfrac{8000}{80}$

$\sf \implies Rs.\; 100$

∴ Cost price of the article is Rs. 100

More to Know :-

✰ Loss = SP - CP

✰ Profit = CP - SP

✰ $\sf Profit \% = \dfrac{Profit}{CP} \times 100\%$

✰ $\sf Loss \% = \dfrac{Loss}{CP} \times 100 \%$

Answer 2

Given :-

• Selling Price of an article is 80
• Loss Percentage of an article is 20%

To Find :-

• Cost Price of an article.

Step-by-Step-Explaination :-

As we know that :-

CP = 100/(100 - Loss % ) × SP

Where,

• Loss Percentage = 20%

• Selling Price (SP) = 80

Putting the respective value,

CP = 100/( 100 - 20% ) × 80

CP = 100/80 × 80

CP = 100

Hence,

The cost price (CP) of an article is = ₹ 100
