Question

Harini buys a sack of rice. It contains 4 kg 500 g of rice. If she uses 2kg 600 g of rice, estimate how much rice is left in the sack (round to the nearest thousands).

• A. 1 kg
• B. 2 kg
• C. 3.5 kg
• D. 4 kg

Answer 1

The correct option is B 2 kg

Total rice bought = 4 kg 500 g

1 kg = 1000 g

4 kg 500 g = 4500 g

Used rice = 2 kg 600 g

2 kg = 2000 g

Used rice = 2600 g

Remaining rice = 4500 - 2600 = 1900

1900 $\to$ 2000 (rounded off to thousands)

Hence, 2 kg of rice is left in the sack.
