(1) F/|F| can be 1 or -1, not enough
(2) G=|F|>0, thus the intial fraction is F/G, not enough

combine: F/|F|=1 or -1

E.

Statement-1 : As others explained, not enough.

Statement-2: G=|F| => G = F OR G= -F
=> |G| = |F| OR |G| = |-F|
=> |G| = F

So the initial fraction F/|G| = F/F = 1. Answer is B.

G=|F| does not imply |G|=F (try G=5 and F=-5)

So, E is the answer.

(1)

|F|/|G| = 1 as both are +ve

F = -1, G = 1

F = 1, G = 1

So not sufficient

(2)

G = |F|, again

F = 1, G = 1

F = -1, G = 1

(1) and (2) together

G = |G|, and G is +ve then, but F can be -ve or +ve, so answer - E.

Statement 1:
If F and G are both positive F/|G| is 1
if F is negative and G is positive F/|G| is -1 ... Thus insufficient

Statement 2: G is always positive but F can either be positive or negative
If F is positive F/|G| is 1
if F is negative F/|G| is -1... Insufficient


Form I &2 :G is always positive but F can either be positive or negative ...Insufficient

E
