Comprehension
Directions for Questions: These questions are based on the situation given below :
There are fifty integers a1 , a2 , ....... a50, not all of them 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.
CAT/1999
Question . 176
All values in S1 are changed in sign, while those in S2 remain unchanged. Which of the following statements is true?
Explanatory Answer
Method of solving this CAT Quantitative Ability Question from Algebra question
S1 = a1 , a2 , ..........a24 S2 = a25................a50 And we also know that L which is the least number has to be in S1 and G which is the greatest number must be in S
(d) With the change in the sign of the members of S1 nothing definitely can be said because if both the sequences contain negative number then each term of S1 will be greater than each term of S2. So the answer must be none of these.
