Set A is {x,2x+y,2y,y+z,x+z}. If x,y, and z are positive integers, then what is the value of the mode of Set A?

1. x is equal to one half of y and twice of z

2. The median of set A is equal to 125.

Please explain your answer _________________

Now all the no. positive integers, so A can be arranged in increasing order. A=(x,1.5x,2.5x,4x,4x) Mode will be 4x

We don't know the value of X, Statement 1 is Insufficient.

From Statement 2:

We don't know the relation between x,y,and Z. So arranging them in order and finding the most repeatitive term in not possible. Statement 2 is Insufficient.
