Out of 180 gym members, is the number of members who attend yoga sessions greater than the number who attend strength training sessions?
(1) Every member who attends yoga sessions also attends at least one other type of session.
(2) Every member who attends yoga sessions also attends strength training sessions.
(1) We don't know the number of sessions that the gym conducts. Let's assume the Gym has three sessions
Yoga, Strength Training and Dance.
Possibility 1: Yoga : all 180 attend ; ST : 30 of 180 and dance : all 180. In this case Y > ST. The answer is yes.
Possibility 2 : Yoga : 30 of 180 ; ST : all 180 and dance : 30 of 180 (all the Yoga ones). In this case Y < ST. The answer is No.
No sufficient.

(2) If Every member who attends yoga sessions also attends strength training sessions., then the number of Yoga cannot be more than the number of strength training. The answer is always no.
This statement alone is sufficient to yield the an answer to the question asked.
