| Number | Repeating Cycle of Sum of Digits of Multiples |
|---|---|
| 7 | {7,5,3,1,8,6,4,2,9} |
| 8 | {8,7,6,5,4,3,2,1,9} |
| 9 | {9,9,9,9,9,9,9,9,9} |
| 10 | {1,2,3,4,5,6,7,8,9} |
How many two digit numbers are there whose sum of digits is 10?
Description for Correct answer: Let the two-digit number be 10x + y. Therefore, Required number is 73. So, the number is a multiple of a number.
How many four digit numbers are there such that the sum of the digits is 10?
There are 219 4-digit numbers whose sum of digits is 10.
How many numbers is 10?
11 digits
So number 10 would have 11 digits.
What is the sum of first 10 even numbers?
110
Therefore, the first 10 even natural numbers will be 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20. Hence, the required sum of the first 10 even natural numbers is 110.
What is the sum of the 10 natural numbers?
Therefore, the sum of the first 10 natural numbers is 55.
How many two digit numbers are there?
The total number of two digit numbers is 90. From 1 to 99 there are 99 numbers, out of which there are 9 one-digit numbers, i.e., 1, 2, 3, 4, 5, 6, 7, 8 and 9. If one digit numbers are subtracted from 99 we get 90 two-digit numbers.
How many numbers are there from 100 to 999?
Hence there are 320 such numbers between 100 and 999 which are odd and have distinct digits. Note: Students should note that at hundreds place zero cannot be placed as no three digit number starts with zero and hence it can be filled by only 8 ways.
How many numbers are there between 999 and 3000?
In between the numbers 999 and 3000, there are totally 2000 four digit numbers. The above series is arithmetic progression. Hence between 999 and 3000 there are 2000 four digits numbers.
How many digits does 10 100 have?
Thus, the answer to your question is that 10100 requires about 333 binary digits. If you want to be more accurate you will have to work harder. The number of digits of a number is revealed when you look at the logarithm of the number using a base equal to the number of possible digits.
What is the smallest 10-digit number?
1,000,000,000
The smallest 10-digit number is written as 1,000,000,000 and is called one billion.
How many integers less than 100 have digit sum equal to N?
It helps to write all positive integers less than 100 as two-digit numbers, where the first digit could be 0. These are 9 such integers: 08, 17, 26, 35, 44, 53, 62, 71, 80. Let n be a positive integer with n < 10. How many positive integers less than 100 have digit sum equal to n?
How many 3 digit numbers have two zeros?
Therefore total number of 3-digit numbers whose sum of digits is 10 = 36 + 9 + 9 = 54. NOTE: 100, 200, ⋯, 900 digits with two zeros are not included in any of these cases.
How many digits are in the tens position?
Each digit from 0 0 to 9 9 appears 100 100 times in the hundreds position. Each digit from 0 0 to 9 9 appears 10 10 times 10 10 times in the tens position. Each digit from 0 0 to 9 9 appears singly 100 100 times in the units position.
How to calculate the number of 3 digit numbers?
Case III: The last digit is zero but other digits are non-zero. (Eg: 190) One of the partitions is at the end and other partition can be chosen from one of the 9 places. The number of choices = ( 9 1) = 9 Therefore total number of 3-digit numbers whose sum of digits is 10 = 36 + 9 + 9 = 54.
