m <=n
m<=m+(nm)x<=n?
(1) x<=n
obviously INSUFF
(2)0<=x<=1
m = 100, n = 200
100 <= 100 + 20,000 * x <= 200
x = .999999 vs x = .00000001
INSUFF

It should be - E
n = 4, m = 3, x = 1/2
3 <= 3 + 4*3*1/2 <= 4 - False
N = 8, m = 1, x = 1/2
1 <= 1 + 1*8*1/2 <= 8
n = 4, m = 3, x = 1/2
3 <= 3 + 4*3*1/2 <= 4 - False
N = 8, m = 1, x = 1/2
1 <= 1 + 1*8*1/2 <= 8
