So y+z>x
2y>x

From2: insufficient

I) diff of other sides <length of side<sum of other two sides

0<x<2y
Sufficient

II)value of x has no impact on question as we don't know value of y

Correct Answer: A
To prove: x>2y
It's a Y/N qs. Testing on "Sum of two sides is greater than the third side".

1. y=z
=> 2y > x
Sufficient

2. 0<x<10
no info about y and z.
Insufficient
