Answer 1

Answer:

The given digit are: 0,3,7 and 9

For smallest number we have to take the digits as following:

The smallest digit at thousand place

0 is the smallest digit ,but if we take 0 at this place then number remains 3 digits

as 0379 =379

So we take next number bigger than 0 which is 3

2. Hundreds place smallest of remaining digits : 0,7,9 (i.e. 0)

3. Tens smallest of remaining digits : 7,9 (i.e. 7)

4. Ones place smallest of remaining digits : 9

So the smallest 4 digit Number becomes
