Solution:
Place value of 3 in 3945 is 3000
Place value of 5 in 3945 is 5
Difference between them = 3000 – 5
= 2995
Hence, the difference between the place value of 3 and 5 in the number 3945 is 2995
4. In the number 40562
(i) the local value of 5 = …………..
(ii) the place value of 6 = ………..
(iii) the sum of the place value of 5 and the place value of 6 = …………
Solution:
(i) The local value of 5 = 500
(ii) The place value of 6 = 60
(iii) The sum of the place value of 5 and the place value of 6 = 500 + 60
= 560
5.Read and write the following numbers in words and also in expanded form :
(i) 35,000 = …………
(ii) 76,000 = ……………
(iii) 6,23,000 = ………….
(iv) 40,075 = …………….

Solution:
(i) 35,000 = Thirty five thousands
3 × 10000 + 5 × 1000
(ii) 76, 000 = Seventy six thousands
7 × 10000 + 6 × 1000
(iii) 6, 23, 000 = Six lakhs twenty three thousands
6 × 100000 + 2 × 10000 + 3 × 1000
(iv) 40, 075 = Forty thousand seventy five
4 × 10000 + 7 × 10 + 5 × 1
(v) 50, 004 = Fifty thousand four
5 × 10000 + 4 × 1
6. Find the difference in the place values of two sevens in the number 8, 72, 574.
Solution:
In the number 8, 72, 574 the first 7 occurs at thousand place

2. Would the number of students in your school be a 3-digit number or a 4-digit number or a 5-digit number?
Solution:
Number of students varies from one school to another school
The total strength of our school is 4410
Hence, it is a 4-digit number
3.Write the smallest number which is just more than 9, 99, 999.
Solution:
Given number = 9, 99, 999
Smallest number which is more than 1 is
9, 99, 999 + 1 = 10, 00, 000
10, 00, 000 is the smallest number which is just more than 9, 99, 999
4. Starting from the greatest 5-digit number, write the previous five numbers in descending order.
Solution:
Greatest 5-digit number = 99, 999
The previous five digit numbers in descending order are 99, 999 > 99, 998 > 99, 997 > 99, 996 > 99, 995 > 99, 994
5. Starting from the smallest 7-digit number, write the next four numbers in ascending order.
Solution:
Smallest 7-digit number = 10, 00, 000
The next four numbers in ascending order are 10, 00, 001 < 10, 00, 002 < 10, 00, 003 < 10, 00, 004.
6.How many numbers lie between the largest 3-digit number and the smallest 4-digit number?
Solution:
Largest 3-digit number = 999
Smallest 4-digit number = 1000
Required number = (1000 – 999)
= 1
Therefore 1 lies between the largest 3-digit number and the smallest 4-digit number.
7.How many 5-digit numbers are there in all?
Solution:
Largest 5-digit number = 99999
Largest 4-digit number = 9999
Required number = 99999 – 9999
= 90, 000
Hence, 90, 000 numbers are there in all
