The digits of 2021 can be rearranged to form other four-digit whole numbers between 1000 and 3000. What is the largest possible differerence between two such four-digit whole numbers?
(A) 1188
(B) 1098
(C) 1080
(D) 2088
(E) 999

Part B: Each correct answer is worth 6.
By assigning the largest digits to the largest place values, we form the largest possible four-digit number.

The largest four-digit number that can be formed by rearranging the digits of 2021 is 2210 .

By assigning the smallest digits to the largest place values, we form the smallest possible fourdigit number.

The smallest four-digit number (greater than 1000) that can be formed by rearranging the digits of 2021 is 1022 .

Thus the largest possible difference between two such four-digit numbers is $2210-1022=1188$.
