gain of Rs. 20
​

Answer 1

Answer:

• Gain percentage on a product is 20 %.

Step-by-step explanation:

Given that:

• Selling price = Rs 120
• Gain = Rs 20

To Find:

• Gain percentage on a product.

Concept:

• For finding the gain percentage of a product first we have to find its cost price.

Formula used:

• CP = SP - Gain
• Gain % = (100 × Gain)/CP

Where,

• CP = Cost price
• SP = Selling price

First finding the cost price of a product:

⟶ CP = Rs 120 - Rs 20

⟶ CP = Rs 100

∴ Cost price of a product = Rs 100

Now finding the gain percentage:

⟶ Gain % = (100 × 20)/100 %

⟶ Gain % = 2000/100 %

⟶ Gain % = 20 %

∴ Gain percentage on a product = 20 %

Answer 2

Answer:

Given :-

• A product when it is sold for Rs 120 with a gain of Rs 20.

To Find :-

• What is gain percentage.

Formula Used :-

$\longmapsto \sf\boxed{\bold{\pink{Cost\: Price =\: Sold\: Price - Profit}}}$

$\longmapsto \sf\boxed{\bold{\pink{Gain\% =\: \bigg(\dfrac{Gain \times 100}{Cost\: Price}\bigg)}}}$

Solution :-

Given :

• Cost Price = Rs 120
• Profit or Gain = Rs 20

According to the question by using the formula we get,

↦ $\sf Cost\: Price =\: Rs(120 - 20)$

➠ $\sf\bold{\green{Cost\: Price =\: Rs\: 100}}$

Now, we have to find the gain percentage :

Given :

• Cost Price = Rs 100
• Gain = Rs 20

According to the question by using the formula we get,

↦ $\sf Gain\% =\: \bigg(\dfrac{20 \times \cancel{100}}{\cancel{100}}\bigg)$

➲ $\sf\bold{\red{Gain\% =\: 20\%}}$

$\therefore$ The gain percentage is 20%.
