There are two sets of numbers Set A and Set B. Is the average of numbers in Set A greater than that of set B?
(1) The smallest value of set A is larger than the smallest value of set B while the largest value of set A is larger than the largest value of set B
(2) If the smallest and largest values of set A are ignored, the average of the remaining numbers in the set is the same as the previous average of allterms
Statement1
(1) The smallest value of set A is larger than the smallest value of set B while the largest value of set A is larger than the largest value of setB
Knowing the relative details of the values will not help us determine whether the average of numbers in Set A greater than that of Set B.
Consider the below twocases:
Case1
A = {0, 10, 20} → Average = 10
B = {-1, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11} → Average = 10
Is the average of numbers in Set A greater than that of set B? →No
Case2
A = {0, 10, 20} → Average = 10
B = {-1, -1} → Average
