Weight Word Problems (Grade 2)
Weight word problems use addition and subtraction to solve questions about how heavy things are. In Class 2, you work with kilograms (kg) and grams (g).
These problems ask you to find the total weight, the difference in weight, or the remaining weight of objects.
What is Weight Word Problems (Grade 2) - Class 2 Maths (Measurement)?
Weight tells us how heavy something is. We measure weight in:
- Grams (g) — for light things like a pencil, an apple, or a packet of biscuits
- Kilograms (kg) — for heavier things like a bag of rice, a suitcase, or a person
1 kilogram = 1000 grams
Solved Examples
Example 1: Total Weight (Addition)
Question: A bag of rice weighs 5 kg. A bag of sugar weighs 2 kg. What is the total weight?
Think:
- Total = 5 + 2 = 7
Answer: The total weight is 7 kg.
Example 2: Difference in Weight (Subtraction)
Question: A watermelon weighs 4 kg. A papaya weighs 1 kg. How much heavier is the watermelon?
Think:
- Difference = 4 − 1 = 3
Answer: The watermelon is 3 kg heavier.
Example 3: Remaining Weight
Question: Ria has 500 g of flour. She uses 200 g to make rotis. How much flour is left?
Think:
- Remaining = 500 − 200 = 300
Answer: 300 g of flour is left.
Example 4: Adding Weights of Items
Question: Dev's school bag weighs 3 kg. His tiffin box weighs 1 kg. His water bottle weighs 1 kg. What is the total weight he carries?
Think:
- Total = 3 + 1 + 1 = 5
Answer: Dev carries 5 kg in total.
Example 5: Comparing Weights
Question: A mango weighs 250 g. An apple weighs 150 g. Which is heavier and by how much?
Think:
- 250 > 150, so the mango is heavier
- Difference = 250 − 150 = 100
Answer: The mango is heavier by 100 g.
Example 6: Word Problem — Shopping
Question: Priya's mother buys 2 kg of potatoes and 3 kg of onions. What is the total weight of vegetables?
Think:
- Total = 2 + 3 = 5
Answer: The total weight is 5 kg.
Example 7: Word Problem — Packets
Question: A packet of biscuits weighs 300 g. Aman buys 2 packets. What is the total weight?
Think:
- 2 packets = 300 + 300 = 600
Answer: The total weight is 600 g.
Key Points to Remember
- Weight is measured in grams (g) for light things and kilograms (kg) for heavy things.
- 1 kg = 1000 g.
- "Total weight" or "altogether" means add.
- "How much heavier" or "difference" means subtract.
- Make sure both weights are in the same unit before adding or subtracting.
Practice Problems
- A bag of apples weighs 3 kg. A bag of oranges weighs 4 kg. What is the total weight?
- Kavi's cat weighs 5 kg. Neha's cat weighs 3 kg. How much heavier is Kavi's cat?
- Meera has 800 g of dal. She uses 350 g for cooking. How much dal is left?
- A book weighs 400 g. A pencil box weighs 200 g. What is the total weight?
- Aditi buys 2 kg of bananas and 1 kg of grapes. How much fruit does she buy in total?
- A box weighs 6 kg. After removing some items, it weighs 2 kg. How much weight was removed?
Frequently Asked Questions
Q1. What units do we use to measure weight in Class 2?
We use grams (g) for light objects and kilograms (kg) for heavier objects. 1 kg = 1000 g.
Q2. How do I know whether to add or subtract in a weight problem?
If the problem asks for total weight, combined weight, or altogether, you add. If it asks how much heavier, lighter, or remaining, you subtract.
Q3. What weighs about 1 kg?
A packet of paneer, a big bottle of water, or a small bag of apples weighs about 1 kg.
Q4. What weighs about 1 gram?
A small paper clip weighs about 1 gram. A ₹1 coin weighs about 3-4 grams.
Q5. Can I add kg and g directly?
No. First convert to the same unit. Either change kg to g (multiply by 1000) or change g to kg (divide by 1000), then add or subtract.
Q6. What tool do we use to measure weight?
We use a weighing scale or balance to measure weight. Digital scales show the weight in numbers.
