The dropdown numbers is an illustration of combination
The smallest dropdown number is 1025
<h3>How to determine the smallest dropdown number?</h3>
From the question, we have the following parameters:
- The dropdown number is 4-digit
- The digits are different.
We start counting from 1023, 1024, 1025, 1026...........
- The sum of digits in 1023 is 6, and the average is 1.5
- The sum of digits in 1024 is 7, and the average is 1.75
- The sum of digits in 1025 is 8, and the average is 2
The number 1025 satisfies the given conditions
Hence, the smallest dropdown number is 1025
