3. Raman bought 3 kg 250 g of tomatoes, 5 kg 110 g of potatoes and 3 kg 750 g of onions. What is the total weight of the vegetables ?

Weight of tomatoes            = 3 kg 250 g

Weight of potatoes             = 5 kg 110 g (+)

Weight of onions                 = 3 kg 750 g

Total weight of vegetables = 12 kg 110 g

Answer: The total weight of the vegetables = 12kg 110g

4. Kannan bought some fruits and vegetables whose total weight is 3 kg 480 g. If the weight of fruits is 1 kg 657 g, find weight of the vegetables.

Total weight                = 3 kg 480 g

Weight of fruit            = 1 kg 657 g (−)

Weight of vegetables   = 1 kg 823 g

Answer: The weight of the vegetables = 1kg 823g

5. The weight of first bag is 1 kg 200 g more than the weight of the second bag. If the weight of the first bag is 3 kg 500 g. Find the weight of the second bag.

Weight of first bag = 3 kg 500 g

Weight of second bag = 3kg 500g − 1 kg 200 g

3 kg 500 g

1 kg 200 g (−)

2 kg 300 g

Answer: Weight of second bag = 2kg 300g
