- AA > D is true
- BThe relation between A and D cannot be determined
- CD > A is true
- DA = D is true
Step-by-Step Solution
'A & B' means A > B, 'B $ C' means B = C, 'C @ D' means C >= D. So A > B = C >= D, which gives A > D.
Answer: A) A > D is true
In a coded inequality, 'M & N' means M > N, 'M $ N' means M = N, and 'M @ N' means M >= N. Given 'A & B', 'B $ C' and 'C @ D', which relation between A and D is definitely true?
