{3, 5, 8, y}
For the above mentioned Set, Mean of the set is equal to Range of the set then find out possible values of y
Choose the correct answer.
A) 16/5, 28/3  B) 4, 16/5  C) 4, 16/5, 28/3  D) 4, 28/3  E) 3, 4, 5
The set can have the following forms:   1. {3,5,8,y} , range = y-3 and mean = 4+y/4, y= 28/3   2. {3,5,y,8} , range = 5 and mean = 4+y/4, y=4   3. {3,y,5,8} , range = 5 and mean = 4+y/4, y=4   4. {y,3,5,8} , range = 8-yand mean = 4+y/4, y=16/5. But as y&lt;3 (assumed here), y=3.2 can not be true. Hence reject this case.   Thus the possible values are 4 and 28/3.   4, 28/3 is the correct answer.
