Answer 1

Answer:

profit % = 20%

Explanation:

CP=SP-Profit

CP=Rs(120-20)

CP=Rs 100

$profit \: percentage = \frac{profit}{cp} \times 100$

$profit \: percentage = \frac{20}{100} \times 100$

profit % = 20%

Answer 2

$\small{\textsf{\textbf{\underline{\underline{∴ Gain percentage on a product = 20•/• \::}}}}}$

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 %
