Direction: In the following questions, the symbols @, ©, # and * are used with the following meaning as illustrated below: |
\['P\,\,\$\,\,Q'\] means ?P is neither smaller than nor equal to Q?. |
\[P\,\,Q\] means ?P is not greater than Q?. |
\[P\,\,*\,\,Q\] means "P is neither greater than nor smaller than Q?. |
\[P\,\,Q\] means ?P is neither greater than nor equal to Q?. |
\[P\,\,Q\] means ?P is neither greater than nor equal to Q?. |
\[P\,\,\#\,\,Q\] means ?P is not smaller than Q?. |
Now in each of the following questions assuming the given statements to be true, find which of the conclusions I, II, III and IV given below then is/are definitely true. |
Statements: \[J\text{ }\$\text{}M,\text{}N\text{}\text{}R,\text{}R\,\,M\] |
Conclusions I. \[N\,\,J\] II. \[N\,\,M\] III. \[J\text{ }\$\text{}R\] IV. \[N\,\,*\,\,R\] |
A) Only I, II and III are true
B) Only I and II are true
C) Only II, III are true
D) Only II and IV are true
E) None of these
Correct Answer: A
Solution :
\[\$=P>Q\] \[=P\le Q\] \[*=P=Q\] \[=P<Q\] \[\text{ }\!\!\#\!\!\text{ }=P\ge Q\] (a) Statements: \[J\text{ }>\text{ }M,\text{ }N\text{ }\le \text{ }R,\text{ }R\text{ }<\text{ }M\] \[\therefore \,\,\text{ }J\text{ }>\text{ }M\text{ }>\text{ }R\text{ }\ge \text{ }N\] Conclusions I. \[N\,\,<\,\,J\] ..?? (3) II. \[N\,\,<\,\,M\] ?...... (3) III.\[J\,\,>\,R\]?..... (3) IV. \[N\,\,=\,\,R\] ?..... (5)You need to login to perform this action.
