Conclusions

I. N*R         II.N$R         III.N$M

  • A.All are true
  • B..Either I or II is true
  • C.Either I or II and III is true
  • D.Either I or III and II is true
  • E.None of these

Answer: C

Correct answer: Either I or II and III is true

Translating: M < R, R ≤ T, T = N, so M < R ≤ N. Since R ≤ N, either N = R or N > R, which makes conclusions I and II a complementary pair - exactly one holds, so either follows. And N ≥ R > M gives N > M, so III is true outright.
