Answer :
The amounts are 16, 8, 4, and 2. Doubling everything with the 16, we can process the numbers step by step:
8, 16, 4, 2
4, 16, 8, 2
2, 16, 8, 4
After making all the changes, these values lead to the last set, so 16, 8, 4, 2 is a working set.
8, 16, 4, 2
4, 16, 8, 2
2, 16, 8, 4
After making all the changes, these values lead to the last set, so 16, 8, 4, 2 is a working set.
