What number should you decrease by 10 times if you decrease the result by 100 and we get a number 10 times less than 100?

Let’s break down the process of counting an unknown number into actions. Let the unknown number be equal to X.

1) Reduce X by a factor of 10 and get X / 10.

2) Reduce the result obtained by 100 and get X / 10 – 100.

3) The final value must be equal to a number that is 10 times less than 100.

4) Divide 100 by 10 and get the number 10, which is 10 times less than 100.

5) Now let’s compare the number obtained in the 2nd and 4th actions.

X / 10 – 100 = 10.

X / 10 = 10 + 100.

X / 10 = 110.

X = 110 * 10.

X = 1100.

As a result, the number 1100 was obtained.

Answer: 1100.
