As per the clausius statement dQ/T <= 0 for irreversible cyclic process. i.e., entropy is always less than zero.

Irreversible means factors are not restored like heat. Hence for irreversible processes entropy increases.

They said increased or decreased they did not mention less than zero or more than zero.

Entropy will remain constant as it point function and here the process is cyclic.

Change in entropy can be < 0.
Change in entropy can be < 0.
