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. J@O |
II. Z©P |
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: B
Solution :
Given statements: \[\text{O }\!\!\#\!\!\text{ S }\Rightarrow \text{ O = S}...\text{(i)}\] \[\text{S }\!\!%\!\!\text{ V }\Rightarrow \text{ S V}...\text{(ii)}\] \[\text{V }\!\!\$\!\!\text{J}\Rightarrow\text{V}\ge\,\,\text{J}...\text{(iii)}\] Combining (i), (ii) and (iii). we get \[\text{O = S V }\ge \text{ J}...\text{(iv)}\] Check for conclusion I. \[\text{J O }\Rightarrow \text{ J }\le \text{ O}\] From (iv),\[\text{O J}\]. But \[\text{O }\ge \text{ J}\] is not true. Check for conclusion II. \[\text{J O }\Rightarrow \text{ J O}\] From (iv), \[\text{O J}\] or \[\text{J O}\] is true.You need to login to perform this action.
