There are 50 integers a1, a2, a3,…,a50; not all of them necessarily different. Let the greatest integer of these 50 integers be referred to as G and smallest integer be referred to as L. The integers a1 to a24 form a sequence S1 and the rest form a sequence S2. Each member of S1 is less than or equal to each member of S2.
Elements of S1 are in ascending order and those of S2 are in descending order. a24 and a25 are interchanged then which of the following is true?
