Answer 1

What is the smallest 4-digit number formed by using the digits 0, 3, 5, 6?

Correct option is

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.

Answer 2

$\huge\sf{\underline{\underline{\underline{\purple{Solution:}}}}}$

3056 is the smallest 4- digit number.

$\sf{\underline{Explanation:}}$

Arrange the number in ascending order then,

= 0,3,5,6.

A number can't begin with 0, so we will put it in second place.

The smalles number other than 0 us 3.

Therefore the number will begin with 3.

Thus, the smallest number formed is 3056.
