| Direction: In the question, the symbols $,\[\delta \], @, % and © are used with the following meanings as illustrated below: |
| 'A $ B' means 'A is neither greater than nor equal to B' |
| 'A \[\delta \] B' means 'A is not greater than B' |
| 'A @ B' means 'A is not smaller than B' |
| 'A % B' means 'A is neither smaller than nor greater than B' |
| 'A©B' means 'A is neither smaller than nor equal to B' In each of the following questions, assuming the given statements to be true, find out which of the conclusions I, II, III and IV given below them is/are definitely true. |
| Conclusions: |
| I. C © Q |
| II. Q $ F |
| III.\[I\,\$\,M\] |
| IV. F% C |
A) Only I
B) Only II
C) Only III and IV
D) All are true
E) None of these
Correct Answer: B
Solution :
Given \[\$\,\to\,<\] \[\delta \to \,\le \] \[\to \,\ge \] \[%\,\to \,=\] \[\bigcirc c\to \,>\] Given statements: C=I...(i) F>I...(ii) \[F\ge M\]..(iii) M>Q...(iv) Combining all these statements, we get \[C=I<F\ge M>Q\] Thus, we can't compare C and Q or I and M. Hence I and III are not true. Again, F > Q or Q < F. Hence II (Q $ F) is true. And C < F or F > C is true. Hence IV (F % C) is not true. So only II is true.
