Distance between 2x and 3x

l3x-2xl = lxl = ????

Statement I
lx-(-x)l = 16
l2xl = 16
lxl = 8

Sufficient.

Statement II

l3x-xl = 16
l2xl = 16
lxl = 8

Sufficient.

Hence D.

Whats the OA?

The answer should be D.

Both (1) and (2) gives |X| = 8. Therefore sufficient.

Can you please provide OA?

Thanks.
