Consider the symbols '*, $, #, @, %' and the various
meanings associated with them asfollows: 'A * B' means ' A is not greater than B' 'A $ B' means 'A is neither greater than nor smaller than 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 neither greater than nor equal to B' Consider the following statements and conclusions and decide which conclusion(s) is/aretrue. Statements: P @ Q; Q # R; R % S Conclusions: I. S # Q II. R % QSolution
Statements: P @ Q; Q # R; R % S After combined- P ≥ Q ; Q > R ; R < S Conclusions: 1. S > Q Hence conclusion I is false 2. R < Q Hence conclusion II is true
