Answer 2

The profit earned by the shopkeeper = ₹30.
The profit percentage = 6.66%

Given:

• 50kg rice costing ₹40.
• 50 kg rice costing ₹50.
• Mixture of the rice sold at ₹48.

To find:
Profit or loss percentage.

Step by step explanation:

→ Formula used:
Profit percentage = Profit earned by shopkeeper * 100
                                  Money earned separately

Step 1:
We will calculate the total amount earned when only 50 kg rice costing ₹40 is sold.
Money earned = 50 * ₹40 ⇒ ₹200.

Step 2:
We will calculate the total amount earned when only 50 kg rice costing ₹50 is sold.
Money earned = 50 * ₹50 ⇒ ₹250.

Step 3:
The total amount earned by the shopkeeper on selling the rice is
₹200 + ₹250 = ₹450.

Step 4:
Now, we will calculate the amount of money earned on selling the rice at ₹48 per kg.
Total amount of rice = 50 + 50 = 100kgs.
Money earned = 100 * ₹48 = ₹480.

Step 5:
₹480 > ₹450.
∴ The profit earned by shopkeeper = 480 - 450
                                                            = ₹ 30.
The profit earned by the shopkeeper = ₹30.

Step 6:
Profit percentage = Profit earned by shopkeeper * 100
                                  Money earned separately
                              = (30/450) * 100
                              = (1/15) * 100
                              = 6.66%    

∴ The profit percentage = 6.66%
