Statements: J $ K, K * T, T @ N, N © R

Conclusions:

  I. J $ T                   II.R * T                  III.N $ K                                IV.R * K

A Only I is true Correct Answer Incorrect Answer
B Only II is true Correct Answer Incorrect Answer
C None is true Correct Answer Incorrect Answer
D Only III is true Correct Answer Incorrect Answer
E All are true Correct Answer Incorrect Answer

Solution

given statements:  J $ K, K * T, T @ N, N © R After converting: J > K, K ≤ T , T < N , N ≥ R After combining: J > K ≤ T < N ≥ R Conclusion a → J $ T → J > T ( J > K ≤ T ) No relationship can be established between J and T so, it is not true. Conclusion b → R * T → R ≤ T (T < N ≥ R) No relationship can be established between R and T so, it is not true. Conclusion c → N $ K → N > K ( K ≤ T < N ), it is true. Conclusion d → R * K → R ≤ K (K ≤ T < N ≥ R) No relationship can be established between R and K so, it is not true.
