An ellipse, a circle and a rectangle overlap in the figure. What is the sum of the numbers lying in exactly two of the figures?

Exactly two figures: 7 (ellipse and circle), 3 (ellipse and rectangle) and 9 (circle and rectangle), so the sum is 19. 25 adds the 6 in all three, 24 is the exactly-one sum $8+5+11$, and 28 adds the 9 twice.
