1. The distance between s and 0 is the same as the distance between t and 0
2. 0 is between s and t.



The answer 2 this question is A.

---------------s-------0--------t--------------
1.If A is true then s=-t
so A is the answer

B is not sufficient

Seems to be A.

(2) does not give us much as s & t could be equal or unequal.
(1) says |s - 0| = |t - 0| or |s| = |t| => s = t or s = -t

As s is not equal to t (from the stem), therefore s = -t or s + t = 0.

Definite A.

The key here is to pick up on "different numbers" in the question.

If 0 is between s and t, I tuk it as 0 is exactly in between s and t....

My answer is A

B is not enough because it is not clear 0 is exactly where from both s,t

1) (s+t)/2 = 0
so, s+t=0
2) between does not mean equal distance.

Question is s+t = 0, s= -t?

S and t are different numbers

(1) |s| = |t|
If S and T have to be different numbers then yes.

S = -t or -t=S, I think both should be equivalent (just multiply each side by 1), Hence s= -t, Suff

(2) Says that 0 is between s and t, so they have different signs, but we don't know anything about their values. Hence Insuff

Answer is (A)
Hope it helps.

By the way, the first time I did this problem I made the mistake in statement 2 of writing that 0 was the average between S and T, but the question stem does not say that 0 is exactly between them, so just to let you know.

If s and t are two different numbers on the number line, is s + t = 0 ?

Note: "the distance between x and y on the number line equals to z" always can be expressed as \(|x-y|=z\).

Given \(s\neq{t}\). Q: \(s+t=0\)? OR is \(s=-t\)

(1) Distance between s and 0 is the same as distance between t and 0 --> \(|s-0|=|t-0|\) --> \(|s|=|t|\). As \(s\neq{t}\), then \(s=-t\). Sufficient.

(2) 0 is between s and t --> 0 is somewhere between s and t on the number line. Not sufficient.

Answer: A.
