(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 ?

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

 

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?

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.
