15 articles:

15 articles = 12x

Find the profit/loss:

Answer 2

Answer:

• Gain % = 25%

Step-by-step explanation:

Given:

• Selling price of 12 articles = Cost price of 15 articles

To Find:

• Gain percent.

Let, the cost price of 1 article = x

It is given that,

⇒ S.P of 12 articles = C.P of 15 articles       ........(1)

Now, the selling price of of 15 articles,

⇒ 12 articles = 15x

Now, the cost price of of 15 articles,

⇒ 15 articles = 12x

Since, selling price is more than cost price. So, it is case of gain.

⇒ Gain = 15x - 12x

⇒ Gain = 3x

Now, we will calculate gain %

$\sf{\implies Gain\; \%=\dfrac{Gain}{C.P}\times 100}$

$\sf{\implies Gain\;\%=\dfrac{3x}{12x}\times 100}$

$\sf{\implies Gain\;\%=\dfrac{100}{4}}$

$\boxed{\boxed{\bf{\implies Gain\;\%=25\;\%}}}$
