Hi souvik101990
I 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.

A. b + d = 2c : Just says c is mid point of b and d. Any value can be closer to zero.

B. d = ‒a : Says a and d are equidistant from 0. But we still cannot be sure which among b,c is closer to zero.

C. c < ‒e : any of d,e can be closer

D. b = ‒d : b and d are equidistant from zero and c can be any value between b and d, which makes it closest to zero. -ANSWER

E. a + b = ‒d ‒ e : any of b,c,d can be closest to zero.

The answer is Option D.

This is similar to a data sufficiency question of the type "Is X ..." . However, isn't very difficult to solve using POE.

A. Let's assume all the integers to be positive (b,d,c =2,5,8) - then "a" must be closest to 0. Now flip the assumption, all the integers are negative (b,d,c =-8,-5,-2) - then "e" must be closest to 0. Hence no clear answer. Reject

B. "d=-a" implies that 0 lies between the two. It could be ab or bc or cd - so we can't be sure of which is closest to 0. Reject

C. This is a little interesting. So either e>-e or -e>e (if e is negative). If -e>e, then 0 lies between them and hence closest to e. However, if e>-e , -e may lie between de or cd. . So 0 will also be between de or cd. No clear answer here. Reject

E. Let's assume e>0 and a,b,c,d<0, then the equation may hold true for a high value of e and 0 will be close to "d". Now let's flip this, a<0 and b,c,d,e>0. Then 0 will be closer to "b". Since no clear answer - Reject

D. b=-d so 0 lies between them. Now since 0 is equidistant from both b and d, it can't be closer to either one of them. Hence closest is c. Since we have a conclusive answer - Accept
