The students in two classes of "Underachiever" high school took a test. x, a, and c are, respectively, the standard deviation, median and the mean of the test scores of the students in class X. y, b, and d are, respectively, the standard deviation, median and mean of the test scores of the students in class Y. Is x>y?

(1) a < b

(2) c < d

IMO E, There is no logic in terms of SD, Mean and Median. Hence we cannot conclude anything even by considering both the choices.

SD depends on how spread out are the elements w.r.t mean.
Combining (1) & (2) also doesn't help achieve that relation. IMO, (E)!
