Q8: The total weight of a bag containing 25 kg 750 g of potatoes and 18 kg 80 g of melon is 44 kg 200 g. How much is the weight of the empty bag?
Step 1: Add weight of potatoes and melon:
Kilograms Grams 25 750 + 18 80 ------------------- 43 830
Step 2: Total weight of filled bag = 44 kg 200 g
Now subtract the content weight from total:
Kilograms Grams 44 200 - 43 830
Since 200 g is less than 830 g, borrow 1 kg = 1000 g:
Kilograms Grams
43 1200 ← (borrowed 1 kg)
- 43 830
-------------------
0 370
Answer: 370 g
Q9: If the school bags of Divya and Rahul weigh 8 kg 60 g and 6 kg 275 g respectively, whose bag is heavier and by how much?
Step 1: We are given:
Divya’s bag = 8 kg 60 g
Rahul’s bag = 6 kg 275 g
Step 2: Compare the weights.
Clearly, Divya’s bag is heavier.
Step 3: Subtract Rahul’s bag weight from Divya’s to find the difference:
Since 60 g < 275 g, borrow 1 kg = 1000 g
So, 8 kg 60 g becomes → 7 kg 1060 g
Kilograms Grams
7 1060
- 6 275
--------------------
1 785
Answer: Divya’s bag is heavier by 1 kg 785 g
Q10: The distance between Naman’s office and his house is 19 km. He covers 14 km 65m by scooter, 3 km 75 m by bus and the rest on foot. How much distance does he cover by walking?
Step 1: Add distance by scooter and by bus:
Kilometres Metres
14 65
+ 3 75
----------------------
17 140
Step 2: Total distance = 19 km = 19 km 0 m
Now subtract 17 km 140 m from 19 km 0 m:
Since 0 m < 140 m, borrow 1 km = 1000 m:
19 km 0 m → 18 km 1000 m
Kilometres Metres
18 1000
- 17 140
----------------------
1 860
Answer: Naman covers 1 km 860 m by walking
Q11: There was an electric wire of length 100 m. Out of it three pieces of length 26 m 85 cm, 3 m 18 cm, 18 m 70 cm were cut off. What is the length of the remaining wire?
Step 1: Add the lengths of the three pieces cut off:
Metres Centimetres 26 85 + 3 18 + 18 70 --------------------- 47 173
Step 2: Since 173 cm = 1 m 73 cm, convert:
47 m 173 cm = 48 m 73 cm
Step 3: Subtract the total cut length from 100 m:
Metres Centimetres 100 00 - 48 73 --------------------- Since 00 < 73, borrow 1 m = 100 cm: 99 100 - 48 73 --------------------- 51 27
Answer: The remaining length of the wire is 51 m 27 cm
Q12: A bag contained 98 kg 300 g of wheat. There was a consumption of 36 kg 450 g, 28 kg 360 g and 32 kg 880 g during three months. How much wheat remains in the bag?
Step 1: Add the consumed quantities:
Kilograms Grams 36 450 + 28 360 + 32 880 --------------------- 96 1690
Step 2: Convert 1690 g = 1 kg 690 g
So total consumption becomes:
96 kg 1690 g = 97 kg 690 g
Step 3: Subtract from the original amount of wheat (98 kg 300 g):
Since 300 g < 690 g, borrow 1 kg = 1000 g:
98 kg 300 g → 97 kg 1300 g
Now subtract:
Kilograms Grams
97 1300
- 97 690
---------------------
0 610
Answer: 610 g of wheat remains in the bag
Q13: Out of 260 litres of milk, a milkman sold 36 l 500 ml, 75 l 750 ml, 68 l 400 ml and 42 l 850 ml. How much milk is left with him?
Step 1: Add the sold quantities:
Litres Millilitres 36 500 + 75 750 + 68 400 + 42 850 ----------------------- 221 2500
Step 2: Convert 2500 ml = 2 litres 500 ml
So,
221 l 2500 ml = 223 l 500 ml
Step 3: Subtract from total milk (260 l 0 ml):
Since 0 ml < 500 ml, borrow 1 litre = 1000 ml:
260 l 0 ml → 259 l 1000 ml
Now subtract:
259 l 1000 ml -223 l 500 ml ------------------- 36 l 500 ml
Answer: 36 litres 500 millilitres of milk is left
