In each of the following questions four statements are given followed by four conclusions marked I, II, Ill and IV. Find which of the conclusions follow the given statements and choose the proper answer choice.
Statements: F $ E; C * R; E ©C; R @ K
Conclusions:
I. E*R
II. C * F
III.E $ K
IV. F + K
Show answer & explanation
Correct answer: B
Explanation
Given:
- F $ E → F < E
- C * R → C > R
- E © C → E = C
- R @ K → R ≤ K
Since E = C and C > R:
E > R → Conclusion I follows. ✅
Also, F < E and E = C:
C > F → Conclusion II follows. ✅
For III, E < K cannot be determined.
For IV, F ≥ K cannot be determined.
Answer: Only I and II follow.
