Solution

The correct option is A 97654153
The greatest eight-digit number containing different digits: 98765432

The smallest seven-digit number consisting the digits 7, 8, 1, and 2: 1111278

The difference between the two numbers = 98765432 − 1111278 = 97654154

Thus, the predecessor of the above number = 97654154 − 1 = 97654153

Hence, the code Will needs to get the bumper prize is 97654153.
