Answer:

Explanation:

The last two digits have to be divisible by 4

The entire number's digits have to add to a multiple of 9. So I will start with 99964

64 does not add up to a multiple of 9. so that's not the answer. 64 is divisible by 4 but not 9

Move on 99968 which has the same problem.

99972 works!!!!
