The Mysterious Chest

8*2 + 6 + 2 = 24

Diamond = 2

Girl = 8

Boots = 6

So:

8x2+(6+2) = 16 + 8 = 24.

This cannot be answered, as the last symbol with he shoe and the single diamond is not defined. Alternatively, if the value of the shoe (=6) is upgraded by the value of the diamond (=2), the final answer would be 24.

The final combination is 24

2+2+2=6

8+8+2=18

6+6-2=10

8x2+8=24

2 + 2 + 2 = 6

8 + 8 + 2 = 18

6 + 6 - 2 = 10

8 * 2 + (6+2) = 24

PS

I assume that the stone is added to the shoe to strengthen it.
