Symbol meanings: P%Q = P=Q; P>Q = P>Q; P©Q = P<Q; P*Q = P≤Q; P@Q = P≥Q. Which expression does NOT lead to 'P≥Q' AND 'M<L' being definitely true?
- P @ R @ Q © M * N L
- P @ R @ Q % M © N © L
- P © R @ Q % M * N * L
- P @ R % Q * M % N © L
Correct answer: P © R @ Q % M * N * L
Solution
Option C: P©R@Q%M*N*L → P<R, R≥Q, Q=M, M≤N, N≤L. Since P<R and R≥Q, we cannot conclude P≥Q (P could be less than Q). P@Q is NOT definitely true. Also M©N©L → M<N<L so M<L ✓ but since P@Q fails, this expression does NOT lead to both conditions being true → this is the answer.
