Correct Answer

Method 1: Add kg and g separately

Step 1: Add the weights: 2 kg 500 g + 1 kg 750 g

Step 2: Add kg: 2 kg + 1 kg = 3 kg

Step 3: Add g: 500 g + 750 g = 1,250 g = 1 kg 250 g

Step 4: Total = 3 kg + 1 kg 250 g = 4 kg 250 g

Method 2: Convert to grams

2,500 g + 1,750 g = 4,250 g = 4 kg 250 g

Answer: Rathna bought a total of 4 kg 250 g of rice.
