Answer: 31
Step-by-step explanation:
The two disks that we know Gina has are: 2 and 8.

This means that the other 3 disks must be the largest possible ones.
We know that Monique has the disks 7 and 9.
The already taken values are: 2, 7, 8, and 9.
The largest values remaining are:
10, 6 and 5.
Then the largest sum that Gyna's disks can have is given by the scenario where Gina draws these 3 disks, and the sum will be:
2 + 8 + 10 + 6 + 5 = 31
