How many 3 digits numbers are there with no repeated?

Answer: There are 648 numbers that are 3 digits numbers such that none of the digits are repeated.

How many even numbers are there with 3 digits such that?

If 3digit even numbers start with 5 then next digit is 7.So numbers are 570,572,574,576,578=5 numbers. Other 3digits numbers can be formed as (1) unit digit can be taken from 0,2,4,6,8 i.e 5 ways. (3)Hundredth digit can be taken from 1 to 9 except 5. Thus 8 possible cases.

How many 3 digit numbers are there each one of which is divisible by 6?

The value of b = 102. The value of n = 6. Thus, the number of 3-digit numbers divisible by 6 is 150.

How many 3 digit even numbers can you form such that one of the digits is 5 then following digit must be 7?

360+5=365 answer. If 3digit even numbers start with 5 then next digit is 7.So numbers are 570,572,574,576,578=5 numbers. Other 3digits numbers can be formed as (1) unit digit can be taken from 0,2,4,6,8 i.e 5 ways.

How many 3 digit even numbers can you form such that if one of the digits is 5 The following is it must be 7?

Given that the number must have a 57 in it and should be even at the same time, the only numbers possible are 570, 572, 574, 576, and 578. Also, if there is no 5 in the number, you will get 360 more numbers.

How many numbers of 3 digits are there which are divisible by 8?

So, number of 3 digit numbers divisible by 8 is 112. Substitute a = 104, d = 8, l = 992 and n = 112. So, the sum of all 3 digit numbers divisible by 8 is 61376.

Is it possible to construct a number which is divisible by 3?

If it is possible then print “Yes” and if not print “No”. Input : arr [] = {40, 50, 90} Output : Yes We can construct a number which is divisible by 3, for example 945000. So the answer is Yes. Input : arr [] = {1, 4} Output : No The only possible numbers are 14 and 41, but both of them are not divisible by 3, so the answer is No.

What is the difference between divisibility and prime number?

Divisibility and Primes Definition. If a and b are integers and there is some integer c such that a = b·c, then we say that b divides a or is a factor or divisor of a and write b|a. Definition (Prime Number).A prime number is an integer greater than 1 whose only positive divisors are itself and 1. A non-prime number

Is the sum of two numbers divisible by 3?
