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)
