Question

In the following question, the symbols $, @, & , % and # are used with the following meanings as illustrated below: ‘A $ B’ means ‘A is neither greater than nor smaller to B’  ‘A @ B’ means ‘A is neither greater than nor equal to B ‘A & B’ means ‘A is neither smaller than nor equal to B ‘A % B’ means ‘A is not smaller than B’   ‘A # B’ means ‘A is not greater than B Now, in each of the following question assuming the given statement to be true, find which of the two conclusions I and II given below them is / are definitely true. Give answer.

Statements: B & X, X # U, U @ K, K % T

Conclusions: I.   X & T                      II. K # B

A If only conclusion I is true. Correct Answer Incorrect Answer
B If only conclusion II is true. Correct Answer Incorrect Answer
C If either conclusion I or II is true. Correct Answer Incorrect Answer
D If neither conclusion I nor II is true. Correct Answer Incorrect Answer
E If both conclusion I and II are true. Correct Answer Incorrect Answer

Solution

Decoded statement: B > X, X ≤ U, U < K, K ≥ T Decoded conclusion I. X > T                            II.  K ≤ B Combined Inequalities: B > X ≤ U < K ≥ T B > X ≤ U < K ≥ T                No relationship can be established between X and T. Hence conclusion I is not true. B > X ≤ U < K ≥ T                No relationship can be established between B and K. Hence conclusion II is not true.
