In a coded inequality system: @ means (greater than) # means

Q: In a coded inequality system: @ means > (greater than) # means < (less than) $ means = (equal to) % means ≥ (greater than or equal to) & means ≤ (less than or equal to) Statement: A % B @ C & D Conclusions: I. A @ D II. B @ D Which conclusion(s) follow?

(B) Only II. Explanation: A≥B>C≤D. B>C≤D means B>C but we can't compare B and D. A≥B>C≤D. For II: B>C and C≤D — we cannot say B>D (D could be ≥C but D vs B is unknown). For I: A≥B>C but D≥C — we can't compare A and D. Answer: Neither follows. Answer D.

Question

In a coded inequality system:
@ means >  (greater than)
# means <  (less than)
$ means =  (equal to)
% means ≥  (greater than or equal to)
& means ≤  (less than or equal to)

Statement: A % B @ C & D
Conclusions:
I.  A @ D
II. B @ D
Which conclusion(s) follow?

Accepted Answer

(B) Only II. Explanation: A≥B>C≤D. B>C≤D means B>C but we can't compare B and D. A≥B>C≤D. For II: B>C and C≤D — we cannot say B>D (D could be ≥C but D vs B is unknown). For I: A≥B>C but D≥C — we can't compare A and D. Answer: Neither follows. Answer D.
