Pg 323 (335) - Q4
You've got positive integers R and S in the problem. Well if that is the case, the value on the left(R) is going to be over the sum of R+S; so, that is going to be a fraction that will be less than 1. The value on the right is (R+S)/R; this will have a value greater than 1. Therefore, B is the correct answer.
