How much extra rice did she buy for household use than for the Pongal festival?

Correct Answer

Calculation: Difference = 2,500 g - 1,750 g = 750 g

Alternative Method: 2 kg 500 g - 1 kg 750 g = 500 g - 750 g (borrow 1 kg) = 500 g + 1,000 g - 750 g = 750 g

Explanation

The chapter explains subtraction of weights. Rice for daily use = 2 kg 500 g = 2,500 g. Rice for Pongal = 1 kg 750 g = 1,750 g. Difference = 2,500 g - 1,750 g = 750 g. Alternatively: 2 kg 500 g - 1 kg 750 g = 500 g - 750 g (borrow 1 kg) = 500 g + 1,000 g - 750 g = 750 g.

Solution Steps

  1. Step 1: Rice for daily use = 2 kg 500 g = 2,500 g

  2. Step 2: Rice for Pongal = 1 kg 750 g = 1,750 g

  3. Step 3: Difference = 2,500 g - 1,750 g = 750 g
