Question

Write the smallest 7 digit number using 4 different digits?

Answer 1

Let’s take four different digits with them being smallest too i.e. 0, 1, 2, 3.

The numerical digit 0 cannot be placed in the first place while forming the number because then the number will have only 6 digits. The idea here is to take from smallest to biggest.

Smallest number other than 0 is 1, so we shall take 1.

Thereby, we shall place 0, (can be repeated four times) then 2 and then 3 will complete 7 digits.

 Thus the smallest 7 digit number with four digits will be 1000023.
