## How many even natural numbers are there between 100 and 1000 with all distinct digits?

How many even integers between 100 and 1000 have distinct digits? But the answer of exercise is 328.

**How many numbers are there between 100 and 1000 which exactly one of the digit as 7?**

Hence, the numbers between 100 and 1000 having the digit 7 exactly once are 72 + 72 + 81 = 225.

### How many numbers are there between 100 and 1000 such that every digit is either 2 or 9?

The first digit can be either 2 or 9; the second digit can be either 2 or 9, and the third digit can be either 2 or 9. Two choices for the first digit, two for the second, and two for the third. 2*2*2 = 8. There are eight such numbers: 222, 229, 292, 299, 922, 929, 992, and 999.

**How many even number are there between 100 to 1000?**

Answer: 899. Between the 2 natural numbers n & m (n>m), there are n-m-1 natural numbers. 1000 -100 = 900. There are 899 Natural numbers between 1000 & 100.

## How many numbers are there between 100 and 1000 which have exactly one of their digits is 5?

225

Now, we take tens place any one of the digits from 0 to 9 except 0 and 5. Therefore, it can be filled in 9 different ways. Hence, there are 9×9=81 numbers. Hence, the number of numbers between 100 and 1000 is 225.

**How many numbers are there between 100 and 1000 which have exactly one of their digits is 8?**

So, it can be filled in 9 different ways. The hundreds place can have any one of the digits except 0 and 7. So, it can be filled in 8 different ways. Therefore, there are 9 x 8 = 72 such numbers.

### How many numbers between 99 and 1000 both excluding can be formed such that there is no restriction?

The digit in hundred’s place can be any one of the 9 digits from 1 to 9. Therefore, by the fundamental principle of counting, there are 10 × 9 = 90 numbers between 99 and 1000 having 7 in the unit’s place.

**How many numbers are there between 99 and 1000 such that there is no restriction?**

Detailed Solution. ∴ The required result will be 90.

## How many numbers between 100 and 1000 have repeated digits?

The third digit can be any of the remaining eight choices, so there are (9) (9) (8) = 648 choices. Since there are 901 numbers between 100 and 1,000, we conclude that 901 – 648 = 253 have repeated digits. Originally Answered: How many numbers are there between 100 and 1000 in which all digits are distinct?

**How many ways can you fill the Hundred’s place with 9 digits?**

We know that a number between 100 and 1000 has three digits. So we have to find all the three digit numbers with distinct digits. We cannot have 0 at the hundred’s place for 3-digit number. So the hundred’s place can be filled with any of the 9 digits. 1,2,3,…..9. So, there are 9 ways of filling the hundred’s place.

### How many distinct digits are there between 9999 and 1000?

How many distinct digits are there between 9999 and 1000? 9999 – 1000 – 1 = 8998. Ie – 1001, 1002, 1003,…,9997, 9998. I think the more likely question though is, how many distinct numbers that are made up of 4 digits, none of which are repeating.

**How many even digits are there in a number?**

In total, there are 5 even digits, one of them including zero. So, the hundred’s place can have 4 different digits (note that zero cannot be in the hundred’s place), the ten’s place can be filled with 5 different digits and one’s place can also be filled with 5 different digits.
