Question

By selling an article for rs 450, a person gains 20 percent, find the c.p​

Answer 1

Answer:

Rs 375

Step-by-step explanation:

Selling price of article = 450

Profit on product = SP - CP = 450 - CP

Profit% = $\frac{Profit}{CP}*100$

⇒ 20 = $\frac{(450-CP)100}{CP}$

⇒ 20CP = 45000-100CP

⇒ 20CP + 100CP = 45000

⇒ 120CP = 45000

⇒ CP = $\frac{45000}{120}$

⇒ CP = 375

∴ Cost price of article = Rs 375
