Question

how many two digit numbers can be formed using three non zero numerals as digits

Answer 1

1,2,3,4,5,6,7,8,9,0 are the digits

Answer 2

Answer:  The answer is 9.

Step-by-step explanation:  We are given to find the number of two digit numbers that can be formed using three non-zero numerals.

Since all the three numerals are non-zero, so we can use any one of them in the ten's place.

Therefore, there are 3 options for the digit in the ten's place.

Similarly, there are 3 options for the digit in the one's place.

So, total number of options for the number is given by

$n=3\times 3=9.$

Thus, 9 two digit numbers can be formed.
