#### Question-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 = …………

(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 = ……………
(iii) 6,23,000 = ………….
(iv) 40,075 = …………….
(v) 50,004 = ………..

(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

Find the difference in the place values of two sevens in the number 8, 72, 574.

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

#### Question -1.

Fill in the blanks :
(i) 999 + 1 = …………
(ii) 10,000 – 1 = …………
(iii) 10 coins – one coin = …………
(iv) ₹ 99 + ₹ 1 = ………..
(v) 10,000 boys – 1 boy = ………..
(vi) 1000 toys – 1 toy = ……….

(i) 999 + 1 = 1,000
(ii) 10,000 – 1 =9,999
(iii) 10 coins – one coin = 9 coins
(iv) ₹ 99 + ₹ 1 = ₹ 100
(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 ?

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.

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.

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.

Smallest 7-digit number = 10, 00, 000

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?

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.
