Concept: The question tests on the basics of absolute value and equations in the format of a DS question
Solution:
St (1)
Given
Distance (t, q) = distance (t, s) + distance (sq.)
t-q shall be positive, as it's the sum of two absolute values. So, t > q.
t > q and s is at the centre, thus q < s < t. Sufficient.
St (2)
It gives no information of s. s>q or s<q. Thus Insufficient.
Option (A)
