Answer 1

Correct Question:

How many different 4- digit number can be fromed using the digits 0 2 4 6 without repeating any digit in the number.

Answer:

48

Step-by-step explanation:

As there are four digits means thousand, hundred, tens and ones are there in it.

If we place 0 at the first position then it will three digit number instead of four digit number. So, we don't have to place 0 at the first position.

So, digits formed will be:

• 2460, 2406, 2046

This method is big. Let's try to do with another method. As there are total 4 digit includes 0, 2, 4, 6. But 0 can't be placed at first position and no one will be repeat again.

Let's say that one number is 1.

So, we have 2, 4, 6, 1.

Hence, total number of 4-digited numbers that can be formed with 0, 2 ,4 and 6 will be 2*4*6*1 = 48
