a) 59 b) 57 c) 55 d) 58
There are fifty integers, a1, a2, …, a50, such that not all of them are necessarily different. Let the greatest integer of these fifty integers be referred to as G, and the smallest integer be referred to as L. The integers a1 through a24 form sequence S1, and the rest form sequence S2. Each member of S1 is less than or equal to each member of S2.All values in S1 are changed in sign, while those in S2 remain unchanged. Which of the following statements is true?
a) Every member of S1 is greater than or equal to every member of S2.
b) G is in S1.
c) If all numbers originally in S1 and S2 had the same sign, then after the change of sign, the largest number of S1 and S2 is in S1.
d) None of the above
