What is the resulting number when the digits at the tens and hundreds place are exchanged in the smallest 4-digit number formed using the digits 2, 0, 8, and 6?

Using the digits 2, 0, 8, and 6 the possible four-digit numbers are 

The number with 0 at the thousands place cannot be considered a four-digit number.

Therefore the smallest 4-digit number formed using the digits 2, 0, 8, and 6 is 2068.

If we exchange the digits at the tens and hundreds places in 2068, we get the number 2608.
