Statements :: R # J, J $ D, D @ K, K % T Conclusions :: I. T # D II. T @ D III. R # K IV. J $ T

Statements
R # J ⇒ R >J
J $ D ⇒ J ≥ D
D @ K ⇒ D = K
K % T ⇒ K ≤ T
i.e., R > J ≥ D = K ≤ T
Conclusions
I. T # D ⇒ T > D       (may be)
II. T @ D ⇒ T = D          (may be)
III. R # K ⇒ R > K           (✔)
IV. J $ T ⇒ J ≥ T             (x)
Hence, either conclusion I or II and III are definitely true.
