In the figure, if A, B, and C are the areas, respectively, of the three nonoverlapping regions formed by the intersection of two circles of equal area, what is the value of B + C?
As the individual areas of both circles are equal,
A + B = B + C
A = C
Statement 1: A + 2B + C = 24
As A = C,
C + 2B + C = 24
2B + 2C = 24
B + C = 12
So, statement 1 is sufficient to answer the question.
Statement 2: A + C = 18 and B = 3.
As A = C,
C + C = 18
C = 9
Statement 2 is sufficient to answer the question.
The correct option is D.
