Class 4 Maths Word Problems Chapter 4 Thousands Around Us

Q1: At a community fair, 567 people attended on Monday, 432 on Tuesday, and 389 on Wednesday. How many people attended in total?
Sol: Total people = 567 + 432 + 389 = 1388.

Q2: A library has 4562 books. Write this number in expanded form using the Indian place value system.
Sol: 4 × 1000 = 4000, 
5 × 100 = 500, 
6 × 10 = 60, 
2 × 1 = 2.
 Expanded form: 4000 + 500 + 60 + 2. 

Q3: A store sold 7893 pens and 7938 pencils. Which item sold more, and by how many?
Sol: Let’s compare the numbers:

• First look at the thousands place:
  7893 has 7, and 7938 also has 7 → so they are the same.

• Now look at the hundreds place:
  7893 has 8, and 7938 has 9 → 9 is bigger than 8.

So, 7938 is bigger than 7893. Therefore, pencils sold more than pens.

Now find the difference:
7938 – 7893 = 45

Q4: A school ordered books: 3456 novels, 3546 textbooks, 3465 comics, and 3564 magazines. Arrange these quantities in ascending order.
Sol: Step 1: Look at the thousands digit of each number:

• 3456 → 3

• 3546 → 3

• 3465 → 3

• 3564 → 3
  All numbers have the same thousands digit, so we move to the hundreds digit.

Step 2: Look at the hundreds digit:

• 3456 → 4

• 3465 → 4

• 3546 → 5

• 3564 → 5
  So, 3456 and 3465 are smaller than 3546 and 3564.

Step 3: Compare 3456 and 3465.

• Look at the tens digit:
  3456 → 5
  3465 → 6
  Since 5 is less than 6, 3456 comes before 3465.

Step 4: Compare 3546 and 3564.

• Look at the tens digit:
  3546 → 4
  3564 → 6
  Since 4 is less than 6, 3546 comes before 3564.

Final answer in ascending order: 3456 novels > 3465 comics > 3546 textbooks > 3564 magazines.

Q5: A factory makes 1200 toys each day. How many toys will it make in 6 days?Sol: Toys made in one day = 1200
Number of days = 6
Total toys made = 1200 × 6 = 7200

Q6: A park’s visitor count follows a pattern: 1500, 1550, 1600, … How many visitors will come on the 4th, 5th, and 6th days?
Sol: Difference: 1550 - 1500 = 50. 
Next: 1600 + 50 = 1650 (4th), 
1650 + 50 = 1700 (5th), 
1700 + 50 = 1750 (6th). 
⇒ 1650, 1700, 1750 visitors.

Q7: A town planted 5432 trees last year and 5678 this year. How many more trees were planted this year?
Sol: Trees this year = 5678
Trees last year = 5432

Ones: 4 (4 small cubes). 
⇒ 3 thousand blocks, 1 hundred block, 2 ten blocks, 4 one blocks.

Q9: In the number 9876, what is the place value of 8 in the Indian system?
Sol: 8 is in the thousands place.
 Place value = 8 × 1000 = 8000.
