Competition practiceInequalities
  • AC is greater than A
  • BB is greater than C
  • CA is greater than C
  • DA is greater than B

Step-by-Step Solution

'A @ B' means A > B and 'B # C' means B < C. The relation between A and C cannot be determined, but A > B is directly given, so 'A is greater than B' is definitely true.
