How many six digit numbers are there in which no digit is repeated even digits appeared in the even places and odd digits in the odd places and the number is divisible by 4?
There are 5760 such numbers.
How many 3 digit numbers can be made using the digits 3 4 5 and 6 if the digits can repeated?
You can make 4*4*4 = 64 numbers.
How many 4-digit numbers can be formed from digits 123456789?
-123456785
How many 6 digit numbers can be formed form the digits 123456 if no digits can be repeated?
6*5*4*3*2*1=720 possible numbers
How many 4 digit numbers have only odd numbers?
625. Here's how:There are five odd digits {1,3,5,7,9} so our numbers will be made using only these digits. This is the same number of possibilities as if you had a base 5 number system where the allowed digits are {0,1,2,3,4}. For a 1 digit base-5, there are 5 possibilities, for a two digit base-5 there are 5² = 25 possibilities, so for a 4-digit, there are 5^4 = 625possible. This is the same number you will have with only using odd digits.
How many six digit numbers are there in which no digit is repeated even digits appeared in the even places and odd digits in the odd places and the number is divisible by 4?
There are 5760 such numbers.
How many four digit numbers can be formed from digits 1 2 3 4 if repeated is allowed and how many are odd numbers?
This is permutations with repetition. The answer is 4^4 = 256 total permutations. Since 2 of the digits used are odd (and 2 are even), then half of the possibilities will be odd: 128 odd numbers.
How many 4 digit numbers can be formed by the digits 1 2 3 4 5 6 7 if the numbers are odd?
4 x 6 x 5 x 4 = 480 if digits are not to be repeated. 4 x 73 = 1372 otherwise.
How many 5 digits can be formed with digits 123456 divisible by 4 with digits not repeated?
192 ways
How many 4 digit numbers can be formed from the digits 7341 if none of the digits can be repeated?
24
How many 3 digit numbers can be made out of the numbers 1 2 3 and 4?
With repeated digits, 43 = 64 Without repeated digits, 4*3*2 = 24
How many 4 digit numbers can be formed from the digits 1234 if any of the digits are not repeated?
That would be 4! = 4 * 3 * 2 * 1 = 24
How many 3 digit numbers can be made using the digits 3 4 5 and 6 if the digits can repeated?
You can make 4*4*4 = 64 numbers.
How many 3 digit numbers can be formed from the digits 24578 if no digits can be repeated?
There are 5*4*3 = 60 such numbers.
How many 4 digit numbers can be formed from digits 123456789?
5040 different 4 digit numbers can be formed with the digits 123456789. This is assuming that no digits are repeated with each combination.
How many 4 digit numbers can be formed by the digits 3 4 6 if any of the digits can be repeated?
3*3*3*3=81
What is the greatest four-digit even number with no repeated digits?
The greatest 4-digit number with no repeated digits is... 9876
