Question

Statements: M $ K, K @ N, N ☆ R, R # W

Conclusions:
I. W @ K
II. M $ R
III. K @ W
IV. M @ N

• A. Only I and II are true
• B. I, II and III are true
• C. Only III and IV are true
• D. II, III and IV are true
• E. None of these

Answer 1

The correct option is E

None of these

$$\begin{array}{cc}Symbol& Meaning\\ ☆& \le \\ \$& \ge \\ \S & =\\ @& >\\ \#& <\end{array}$$
We get, M $\ge$ K > N $\le$ R < W and relation between W, K / M, R / K, W cannot be ascertained.
Hence, only conclusion IV is true and this option is not given.
So, 'none of these' is the correct option.
