In the questions given below, certain symbols are used with the following meanings.
A@ B means A is not greater than B.
A + B means A is not lesser than B.
A © B means A is equal to B.
A $ B means A is neither greater than nor equal to B.
A * B means A is neither lesser than nor equal to B.
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: H @ A; D @ B; T * D; N + A
Conclusions:
I.H©D
II. T@ A
III. N + T
IV. A $ D
Show answer & explanation
Correct answer: D
Explanation
Correct Answer: None of the conclusions follow
Solution:
First, convert the symbols:
-
A @ B → A ≤ B
-
A + B → A ≥ B
-
A © B → A = B
-
A $ B → A < B
-
A * B → A > B
Given Statements:
-
H @ A → H ≤ A
-
D @ B → D ≤ B
-
T * D → T > D
-
N + A → N ≥ A
Checking the conclusions:
-
I. H © D → H = D → Does not follow
-
II. T @ A → T ≤ A → Does not follow
-
III. N + T → N ≥ T → Does not follow
-
IV. A $ D → A < D → Does not follow
Therefore, none of Conclusions I, II, III and IV follows from the given statements.
