Question

How many 6 digit number can be formed divisible by 10?

Answer 1

72 numbers can be formed....i think so

Answer 2

Answer:

90000

Step-by-step explanation:

The first digit cannot be 0, otherwise we wouldn't call it a 6 digit number.

So there are 9 ways of choosing the first digit.

There are 10 ways of choosing the second digit though.

Then 10 ways of choosing the third digit.

10 ways of choosing the fourth digit.

And 10 ways of choosing the fifth digit.

Since the number is to be divisible by 10, we have no choice for the sixth digit, which must be 0.

In total, the number of choices are

9 x 10 x 10 x 10 x 10 = 90000
