Question

An article was sold for Rs. 250 with a profit of 15%. What was its cost
price?​

Answer 1

Given

→ SP = Rs. 250

→ Profit = 15 %

To find :-

CP

Solution :-

To find the profit % , the formula is

( SP - CP/CP) × 100

ATQ ,

{(250 - CP) / CP } × 100 = 15

⇒ (2500 - 100 CP) / CP = 15

⇒ 15 CP = 2500 - 100 CP

⇒ 115 CP = 2500

⇒ CP = 2500 / 115 = 500/23 = Rs. 21.78 (approx)

$\boxed{\red{Cost \: Price \: of \: an \: article \: is \: Rs.21.78}}$
