Question

11. An article was sold for 540 with a profit of 20%. What was its cost price?​

Answer 1

Answer:

432 is the price.

Step-by-step explanation:

Its cost at which it was sold= 540

Percentage of profit= 20%

Therefore it's original price=

20/100 * 540= 108

∴ The original sale price=  540-108

⇒ 432 is the original price without 20% profit.

Answer 2

Answer:

Real cost price of the article is 450 unit

Step-by-step explanation:

we have to find the real cost price of the article

let us assume the cost price of the article be x unit

now to find 20% of x = 20x/100 = x/5

the article was sold at 20% profit

then selling price of the article is (x + x/5) unit

according to question the article was sold for 540 unit

hence x + x/5 = 540

⇒ (5x+x) / 5 = 540

⇒ 6x = 540 × 5

⇒ x = 90 × 5

⇒ x = 450

therefore real cost price of the article is 450 unit
