The following functions have been defined :
la (x, y, z) = min (x + y, y + z)
le (x, y, z) = max (x – y, y – z)
ma (x, y, z) = (½) [le (x, y, z) + la (x, y, z)]
Given that x > y > z > 0, which of the following is necessarily true?
A : la (x, y, z) < le (x, y, z)B : ma (x, y, z) < la (x, y, z)C : ma (x, y, z) < le (x, y, z)D : None of these
