in a list of 7 integers,one integer,denoted as,x is unknown.The other six integers are 20,4,10,4,8 n 4.if the mean,median n mode of these seven integers are arranged in increasing order,they form an arithmetic progression.The sum of all possible wayes of X is?
A)26 B)32 C)34 D)38 E)40

• Numbers are 4,4,4,8,10,20,(x)
  
  Case 1: When x4 and x8
  Mode=4 median=8 Mean>8
  To form an AP.. Mean=12
  
  Hence, value of x=12*7-(4+4+4+8+10+20) = 34
  
  So, two possible values are 6 and 34.
  Sum=6+34=40
