Answer these questions based on the following information. There are 250 integers a1, a2,… a250, not all of them necessarily different. Let the greatest integer of these 250 integers be referred to as Max, and the smallest integer be referred to as Min. 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.All values in A are changed in sign, while those in B remain unchanged. Which of the following statements is true? (a) Every member of A is greater than or equal to every member of B. (b) Max is in A. (c) If all 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. (d) None of these |

Answer» Correct option (d) None of these Explanation: All members of A are smaller than all members of B. In order to visualise the effect of the change in sign in k assume that A is {1, 2, 3...124} and B is {126, 12.7...250}. It can be seen that for this assumption of values neither options (a), (b) or (c) is correct. |
