1.	If it is asked that write the smallest 4 digit number using 4 different digits, then can we use the digits 0?
Answer» Write the smallest 4 digit number FORMED USING the digits 8,3,0,1. (1) 1038 (2) 1308 (3) 1083 (4) 0138. (We can see that this is not a four digit number as 0138 is just SIMPLY 138) Since we NEED a 4-digit number so it cannot start with 0. Hence we can place 0 in the second position.
