Question
Statements: M * T, D % T, D # K, K $ R
Conclusions: I. M * D     II. T # K                               III. K * M             IV. R @ T In these questions, symbols $, *, #, % and @ are used with different meaning as follows: ‘X $ Y’ means ‘X is not smaller than Y.’ ‘X * Y’ means ‘X’ is greater than Y’. ‘X # Y’ means ‘X’ is not greater than Y’. ‘X % Y’ means ‘X’ is smaller than Y’. ‘X @ Y’ means ‘X is neither smaller than nor greater than Y.’Solution
given statements: M * T, D % T, D # K, K $ R After converting: M > T, D < T, D ≤ K, K ≥ R After combining: M > T > D ≤ K ≥ R Conclusion a → M * D → M > D ( M > T > D) , it is true. Conclusion b → T # K → T ≤ K ( T > D ≤ K) No relationship can be established between T and K so, it is not true. Conclusion c → K * M → K > M ( M > T > D ≤ K ) , No relationship can be established between K and M so, it is not true. Conclusion d → R @ T → R = T ( T > D ≤ K ≥ R), No relationship can be established between R and T so, it is not true.
