- Rs. 510
- Rs. 450
- Rs. 485
- Rs. 525

Best answer

**Answer: (1) Rs. 510**

**Explanation:- **

The cost price of 1 kg rice = Rs. 70

Therefore, the cost price of 30 kg rice = 70 x 30

= Rs. 2100

The cost price of 1 kg other quality rice = Rs. 70.75

Therefore, the cost price of 20 kg rice = 20 x 70.75

= Rs. 1415

Then, the total cost price of rice = 2100 + 1415

= Rs. 3515

If he mixed two brand of rice,

Then, the selling price of mixture = Rs. 80.50

Therefore, the total selling price of rice = 80.50 x ( 30 + 20)

= 80.50 x 50

= Rs. 4025

Gain = 4025 – 3515

= Rs. 510

Hence, the answer is (1) Rs. 510.
