Direction: In the following question, the symbols @, ©, %, $ and # are used with the following meanings as illustrated below: |
'X©Y' means 'X is neither greater than nor equal to Y'. |
'X@Y' means 'X is not greater than Y'. |
'X%Y' means 'X is neither smaller than nor equal to Y'. |
'X$Y' means 'X is not smaller than Y'. |
'X#Y' means 'X is neither greater nor smaller than Y'. |
Now in each of these questions assuming the given statements to be true, find which of the conclusions given below them is/are definitely true. |
Give answer |
I. Q # A |
II. Q % A |
A) if only Conclusion I is true.
B) if only Conclusion II is true.
C) if either Conclusion I or II is true.
D) if neither Conclusion I nor II is true.
E) if both Conclusion I and II are true.
Correct Answer: D
Solution :
Given statements; \[\text{A B }\Rightarrow \text{ A }\le \text{ B}...\text{ (i)}\] \[\text{B }\!\!\$\!\!\text{Q}\Rightarrow\text{B}\ge\text{Q}...\text{(ii)}\] \[\text{Q U }\Rightarrow \text{ Q U}...\text{(iii)}\] Combining (i), (ii) and (iii), we get \[\text{A }\le \text{ B }\ge \text{ Q U}...\text{(iv)}\] Check for conclusion I. \[\text{Q }\!\!\#\!\!\text{ A }\Rightarrow \text{ Q = A}\] From (iv). we can't compare Q and A. Thus, Q = A is not true. Check for conclusion II. \[\text{Q }\!\!%\!\!\text{ A }\Rightarrow \text{ Q A}\] From (iv), we can't compare Q and A. Thus, \[\text{Q A}\]is not true.You need to login to perform this action.
