In a code, 'A @ B' means A is greater than B; 'A # B' means A is less than B; 'A % B' means A is equal to B; 'A & B' means A is greater than or equal to B; 'A * B' means A is less than or equal to B. Given M # N, N * O, O @ P, which conclusion is definitely true?

  • A
  • BP < N
  • CN > O
  • DO > M

Step-by-Step Solution

Decoding gives M < N ≤ O and O > P. From M < N ≤ O we get M < O, i.e. O > M. No definite relation exists between P and N or between M and P, and N ≤ O rules out N > O.
Answer: D) O > M
