q)On the number line shown above, is zero halfway between r and s?

(1) s is to the right of 0
(2) the distance between t and r is same as the dis b\w t and -s.
1) is clearly not sufficient

2) t-r = t+s [this can be framed only because they have given the number line]
-r=s
Sufficient to answer the question!

B
