Question
Statements: M @ N % Z # C & B $ A # E;
W $ Z @ C Conclusions : I. E @ Z II. A # W III. M @ C In the following questions, the symbols %, $, #, @ and & are used with the following meaning as illustrated below: ‘Y%Z’ means ‘Y is not smaller than Z’. ‘Y$Z’ means ‘Y is not greater than Z’. ‘Y#Z’ means ‘Y is neither greater than nor equal to Z’. ‘Y@Z’ means ‘Y is neither smaller than nor equal to Z’. ‘Y & Z’ means ‘ Y is neither greater than nor smaller than Z’. Now in each of the following questions assuming the given statements to be true, for conclusions I, II and III given below them is/are definitely true? Give answerSolution
Decoding: Statements: M > N ≥ Z < C = B ≤ A < E; W ≤ Z > C Conclusions : I. E > Z II. A < W III. M > C M > N ≥ Z < C = B ≤ A < E E > Z. Hence, conclusion I follows. W ≤ Z < C = B ≤ A < E A > W. Hence, conclusion II will not follow. M > N ≥ Z < C No relationship can be established between M and C. Hence, conclusion III will not follow.
