Answer 2

There are 90 two-digit natural numbers overall.

Given:

Natural numbers

To find:

Total of 2-digit natural numbers in all =?

Solution:

To find the correct answer to such a question we need to first understand the concept of natural numbers and then check for all the two-digit numbers.

Step 1. Natural Numbers:

All the positive numbers that can be counted are called natural numbers.  It includes all numbers: 1, 2, 3, 4, and so on. 0 is not included in this.

Step 2. Two-digit Numbers:

All the numbers starting from 10 to 99 are two-digit numbers. A number before 10 is a one-digit natural number so not included in this. The number after 99 is a three-digit number and therefore not included as well.

Step 3. Two-digit natural Numbers:

=> 10, 11, 12, 13, (..) 99

=> 99 - 10 = 89

=> 89 + 1 = 90 (Because 10 is also to be included)

Hence, the answer is 90 numbers.
