The following operations are defined for real numbers.
\(A \text{@}B = A\) if A is greater than B else \(A \text{@}B= B\)
\(A \% B = AB\) if A x B is positive else \(A \% B = A\)

Given: A@B = A if A > B else A@B = B.
Also, A%B = AB if AB > 0 else A%B = A.
[( – 4)@( – 5)]%2 = ?
( – 4)@( – 5) = -4 [because -4 > -5]
=> [( – 4)@( – 5)]%2 = (-4)%2
(-4)%2 = -4 [because (-4) * 2 = -8 < 0]
=> [( – 4)@( – 5)]%2 = -4
So, correct answer is option D.

Given that \(A \text{@}B = A\) if A is greater than B else \(A \text{@}B= B\) and \(A \% B = AB\) if A x B is positive else \(A \% B = A\) and we need to find the value of \([( – 4)@( – 5)]\%2\)
Lets start by finding the value of ( – 4)@( – 5)
To find ( – 4)@( – 5) we need to compare what is before and after \(\text{@}\) in ( – 4)@( – 5) and A@B
=> We need to substitute A with -4 and B with -5 in A@B to get the value of ( – 4)@( – 5)
Since A(-4) > B(-5)
=> ( – 4)@( – 5) = -4
=> \([( – 4)@( – 5)]\%2\) = \(-4\%2\)
Here A = -4 and B = -2 => A*B = -4*2 = -8 => NOT POSITIVE
=> \(-4\%2\) = -4
So, Answer will be D
Hope it helps!
