Find Numbers Below 43,125: Odd Tens of Thousands Digit Challenge

Which number is less than 43,125 and has an odd tens of thousands digit?

To solve this problem, let's follow these steps to determine the correct choice:

• Step 1: Identify if the number is less than 43,125.
• Step 2: Check if the tens of thousands digit is odd.

Step 1: Let's evaluate each given choice based on the condition that the number must be less than 43,125:

• Option 1: $26,999$ is less than 43,125.
• Option 2: $32,100$ is less than 43,125.
• Option 3: $54,123$ is greater than 43,125.
• Option 4: $2,450$ is less than 43,125.

Step 2: Now let's check the tens of thousands digit for oddness:

• Option 1: $26,999$ has a tens of thousands digit of 2 (even).
• Option 2: $32,100$ has a tens of thousands digit of 3 (odd).
• Option 3: $54,123$ has a tens of thousands digit of 5 (odd) but doesn't satisfy condition 1.
• Option 4: $2,450$ has a tens of thousands digit of 0 (even).

From these evaluations, only $32,100$ is less than 43,125 and has an odd tens of thousands digit of 3.

Therefore, the solution to the problem is $32,100$.
