Answer-4
(i) the local value of 5 = 500 and its local value is 5.
(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
Question- 5.
Read and write the following numbers in words and also in expanded form :
(i) 35,000 = …………
(ii) 76,000 = ……………

(v) 50,004 = ………..
Answer-5
(i) 35,000 = Thirty five thousands = 3 x 10000 + 5 x 1000
(ii) 76,000 = Seventy six thousands = 7 x 10000 + 6 x 1000
(iii) 6,23,000 = Six lakhs twenty three thousands = 6 x 100000 + 23 x 1000
(iv) 40,075 = Forty thousands seventy five = 4 x 10000 + 75 x 10 + 5
(v) 50,004 = Fifty thousands four = 5 x 10000 + 4
Question-6
Answer-6
In 8,72,574, the first 7 occurs at ten thousand place.
=> Its place value = 70000
=> The second 7 occurs at ten’s place.
Its place value = 70
The difference of the two place values of 7 = 70000 – 70 = 69930
Exercise – 4 B Selina Concise Solutions of Place Value for ICSE Mathematics Class-6th

(v) 10,000 boys – 1 boy = 9,999 boys
(vi) 1000 toys – 1 toy = 999 toys
Question -2.
Would the number of students in your school be a 3-digit number or a 4-digit number or a 5-digit number ?
Answer-2
Attention : This answer will vary from school to school. (contact your school teacher)
Question -3.
Write the smallest number which is just more than 9, 99, 999.
Answer-3
Smallest number which is 1 more than 9, 99, 999 is = 9, 99, 999 + 1 = 10, 00, 000
Question -4.
Starting from the greatest 5-digit number, write the previous five numbers in descending order.
Answer-4
Greatest digit number = 99, 999
Next four numbers in descending order can be obtain by subtracting 1 from 99, 999 and then again subtract 1 from previous result till 4 step
99, 999-1= 99998
99, 998-1= 99997
99, 997-1= 99996
99, 996-1= 99995
Hence four numbers in descending order from 99, 999 are 99998 > 99997 > 99996 > 99995
Question- 5.
Starting from the smallest 7-digit number, write the next four numbers in ascending order.
Answer-5
Next four numbers in ascending order. can be obtain by adding 1 to 10, 00, 000 and then again add 1 from previous result till 4 step
10, 00, 000 + 1 = 10,00,001
10, 00, 001 + 1 = 10,00,002
10, 00, 002 + 1 = 10,00,003
10, 00, 003 + 1 = 10,00,004
Hence next four numbers in ascending order. from 10, 00, 000 are 10,00,001 < 1000002 < 1000003 < 1000004 <1000005
Question-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 = (Smallest 4-digit number – Largest 3-digit number)
= (1000 – 999)
= 1
Question -7.
How many 5-digit numbers are there in all?
Answer-7
Largest number of 5-digits = 99999
Largest number of 4-digits = 9999
Required number= Largest number of 5-digits – Largest number of 4-digits
= 99999 – 9999
= 90,000
So, 90,000 numbers are there in all.
