Question

Write the smallest $4$ digit number formed using the digits $8,3,0,1$.

• A. $1038$
• B. $1308$
• C. $1083$
• D. $0138$

Answer 1

Answer: (A)

$1038$

The ascending order of the given numbers $8,3,0,1$ is:

$0<1<3<8$

A number cannot begin with $0$, so we will put it in the second place.

The smallest digit (other than $0$) is $1$.

Therefore, the number will begin with $1$.

Thus, the smallest number formed is $1038$.

Hence, the smallest $4$ digit number formed is $1038$.
