Answer 2

Given:

A number is multiplied by 100 and divided by 1000

To find:

The resultant number

Solution:

The resultant number is 0.1 times the original number.

We can find the number by following the given steps-

Let us assume that the original number is X.

We know that the number is multiplied by 100 and then divided by 1000.

On multiplying by 100, we get

=X×100

=100X

Now dividing this by 1000, we get

=100X/1000

=X/10

=0.X

=0.1×X

It is 0.1 times the original number.

Therefore, the resultant number is 0.1 times the original number. (Option A)
