Show answer & explanation
Correct answer: C
Answer: 13
Explanation:
Identify the three regions that are shared by exactly two shapes (pairwise overlaps):
Between the circle and the square: 7
Between the square and the triangle: 4
Between the circle and the triangle: 2
Do not include the central 5 because it is inside all three shapes, and do not include numbers that lie in only one shape (for example the numbers visible only in the square or only in the triangle).
Sum the pairwise-only numbers: 7 + 4 + 2 = 13.
