Q6: A bag of flour weighs 5 kg 250 g. Another bag weighs 4 kg 800 g. What is the total weight? (2 Marks)
Solution:
Bag 1 = 5 kg 250 g
Bag 2 = 4 kg 800 g
Add = 5 kg 250 g + 4 kg 800 g = 10 kg 50 g
So, total weight = 10 kg 50 g

Q7: A bottle holds 1 L 500 ml of juice. What is the total juice in 30 bottles?  (2 Marks)
Solution:
One bottle = 1.5 L
30 bottles = 1.5 × 30 = 45 L
So, total juice = 45 L

Q8: A sack of rice weighs 25 kg. If 9 kg 400 g is used, how much rice is left? ​ (2 Marks)​​​
Solution:
Total = 25 kg
Used = 9 kg 400 g = 9.4 kg

So, left rice = 15 kg 600 g

Q9: A sack of sugar weighs 84 kg. If it is divided into 14 equal parts, what is the weight of each part?  (3 Marks)

Q10. A milk tank contains 45 L of milk. Out of this, 18 L 500 ml is used for sweets. The rest is filled into bottles of 2.5 L each. How many bottles can be filled?  (3 Marks)
Solution:
Total milk = 45 L
Used = 18.5 L

Each bottle = 2.5 L
Number of bottles = 26.5 ÷ 2.5 = 10 bottles with 0.5 L left.

​Q11. A fruit seller bought 8 boxes of oranges. Each box weighs 9 kg 750 g. During transport, 5 kg 500 g got spoiled. What is the weight of good oranges?  (3 Marks)

Solution: 

A) 7 × 1000 = 7000 mL

B) 8500 ÷ 1000 = 8.5 L

C) 3 × 1000 = 3000 g

D) 5600 ÷ 1000 = 5.6 kg

E) (8 × 1000) + 250 = 8000 + 250 = 8250 g

Q13: Calculate the following:  (5 Marks)

A) 4576 + 2894 – 1345 =
B) 8421 – 3278 + 1654 =
C) 4567 + 3789 – 2896 =
D) 12000 – 7896 + 4523 =
E) 6789 + 2345 – 1234 =

Solution:

A) 4576 + 2894 = 7470 
→ 7470 – 1345 = 6125

B) 8421 – 3278 = 5143 
→ 5143 + 1654 = 6797

C) 4567 + 3789 = 8356 
→ 8356 – 2896 = 5460

D) 12000 – 7896 = 4104 
→ 4104 + 4523 = 8627

E) 6789 + 2345 = 9134 
→ 9134 – 1234 = 7900
