Answer 2

The cost price of article=Rs 2500

Step-by-step explanation:

Discount=10%

Printed price=Rs 3000

Discount amount=10% of Rs 3000=$\frac{10}{100}\times 3000=Rs 300$

Price of article after discount=Rs 3000-Rs 300=Rs 2700

Profit=8%

S.P of article=Rs 2700

C.P=$\frac{100}{profit(in\;percentage)+100}\times S.P$

Using the formula

C.P of the article=$\frac{100}{8+100}\times 2700=$Rs 2500

Hence, the cost price of article=Rs 2500
