how many three digit whole numbers are there between 90 and 900
Answers
Step-by-step explanation:
The formula that we are going to use for solving this question is as follows:-
(Greatest4–digitnumber)–(Smallest4–digitnumber) + 1
In fact, to find the number of numbers between any two given numbers, we use the same formula.
The smallest four digit number = 1000
The greatest four digit number = 9999
Total four digit numbers = (9999 – 1000) + 1
= 8999 + 1 = 9000
Therefore, there are 9000 four digit numbers in all.
Hence, the answer of this question is (c) 9000.
NOTE:-
To find the number of objects between two limits, that are the upper limit and the lower limit, we use the following formula:-
(Upperlimit)–(Lowerlimit) + 1
Let us now find out the total number of three – digit numbers.
The smallest three digit number = 100
The greatest three digit number = 999
Total three digit numbers = (999 – 100) + 1
= 899 + 1 = 900
So, the total number of three – digit numbers is 900.
Let us now find out the total number of 2 – digit numbers.
The smallest two – digit number = 10
The greatest two – digit number = 99
Total three – digit numbers = (99 – 10) + 1
= 89 + 1 = 90
So, the total number of two – digit numbers is 90.
