Answer 2

Let Cost Price of the article be p.

According to the Question

Loss = 20%

Selling Price = ₹ 320

Formula Loss = CP - SP

Loss = (p - 320).

Using Formula

= $\bf\huge Loss = \frac{Loss}{CP} \times100$

$\bf\huge 20 = \frac{p-320}{p}\times100$

⇒ p = 5p - 1600

⇒ 4p =  1600

⇒ p = 400

The Cost Price of the article is ₹400
