There are 250 integers a1 , a2, ..........a250, not all of them are necessarily different.let the greatest integer of these 250 integers be referred to as maximum and the smallest integer be referred to as Minimum.The integers a1 through a124 form sequence A and the rest form sequence B.Each member of A is less than or equal to each member of B.if all values in A are changed in sign , while those in B remains unchanged.which of the following statement is true?
1.Every member of A is greater than or equal to every member of B
2.Maximum is in A
3.if all the numbers originally in A and B had the same sign, then after the change of sign, the largest number of A and B is in A
4.None of these.
