In a code: 'X @ Y' means X > Y; 'X # Y' means X ≥ Y; 'X $ Y' means X = Y; 'X % Y' means X < Y; 'X & Y' means X ≤ Y. Given the statements 'M @ N', 'N $ O' and 'O # P', which of the following is definitely true?

Competition practiceInequalities
  • AO @ M
  • BN % P
  • CM @ P
  • DP @ M

Step-by-Step Solution

Decoding gives M > N, N = O and O ≥ P, i.e. M > N = O ≥ P, so M > P, which is written as 'M @ P'.
Answer: C) M @ P
