Hi
souvik101990I think we are missing 'equal to' signs here. Correct me if I am wrong. Question should go like this:
A. b + d = 2c ---c is average of b and d. No info on no. closest to zero.
B. d = ‒a --- b or c can be closest so not sure.
C. c < ‒e -----Either d or e could be closest to zero. Not sufficient.
D. b = ‒d ----Only c can be closest to zero. Sufficient.
E. a + b = ‒d ‒ e ----Cannot determine since only sum is equal.
Answer D.
