A solid body of constant heat capacity $1J/{}^ \circ C$ is being heated by keeping it in contact with reservoirs in two ways: $(i)$ Sequentially keeping in contact with $2$ reservoirs such that each reservoir $\,\,\,\,\,\,\,\,$ supplies same amount of heat. $(ii)$ Sequentially keeping in contact with $8$ reservoirs such that each reservoir $\,\,\,\,\,\,\,\,\,\,$ supplies same amount of heat. In both the cases body is brought from initial temperature ${100^ \circ }C$ to final temperature ${200^ \circ }C$. Entropy change of the body in the two cases respectively is :
