Statements :: T % R, R $ M, M @ D, D © H Conclusions :: I. D % R II. H # R III. T © M IV. T % D

Statements
T % R ⇒ T ≤ R
R $ M ⇒ R ≥ M
M @ D ⇒ M = D
D © H ⇒ D < H
i.e., T ≤ R ≥ M = D < H
Conclusions
I. D % R ⇒ D ≤ R         (✔)
II. H # R ⇒ H > R           (x)
III. T ©M ⇒ T < M           (x)
IV. T % D ⇒ T ≤ D          (x)
Hence conclusion I is definitely true.
