Re: Is T/S > F/G? (1) T < S (2) F > G [#permalink]

Is \(\frac{T}{S} > \frac{F}{G}\)?

(1) \(T < S\)

This statement is clearly insufficient, as we know nothing about F and G.

(2) \(F > G\)

Similarly, this statement is clearly insufficient, as we know nothing about T and S.

(1)+(2) It's crucial to note that we don't know the signs of T, S, F, and G. If we were given that S and G are positive, then from (1) we'd infer that \(\frac{T}{S} < 1\), and from (2) we'd infer that \(\frac{F}{G} > 1\), which would lead to \(\frac{T}{S} < 1 < \frac{F}{G}\). For instance, consider \(T = 1\), \(S = 2\), \(G =1\) and \(F = 2\). However, if S and G are negative, then from (1) we'd infer that \(\frac{T}{S} > 1\), and from (2) we'd infer that \(\frac{F}{G} < 1\), which would lead to \(\frac{T}{S} > 1 > \frac{F}{G}\). For instance, consider \(T = -2\), \(S = -1\), \(G =-2\) and \(F = -1\). Not sufficient.

Is \(\frac{T}{S} > \frac{F}{G}\)?


(1) \(T < S\)

(2) \(F > G\)


Understanding Statement 1 alone:
As relation between F and G is not known, the statement alone is insufficient.

Understanding Statement 2 alone:
As relation between T and S is not known, the statement alone is insufficient.

Understanding Statement 1 and 2 together:
Using values:
When T = 4, S = 5, G = 1 and F = 2, then T/S>F/G is true
When T = -4, S = 5, G = 1 and F = 2, then T/S>F/G is false
Insufficient

E is correct
