Ans (E)
Since the Q.S. gives the total number of gym members. Thus, we need to find out whether Y>G.
The Question does not anywhere state that Yoga and Strength training are the only types of sessions available.
Thus, we cannot say that y+g= definitively.
Statement 1 states that people who do yoga are engaged in at least 1 other session. Thus, members who do yoga could be 180 could be 110 could be 10.
Not Sufficient
Statement 2 states that members who attend yoga also attend strength training. Thus, we are faced with the same problem as no definite number can be taken.
Not sufficient
When taking Statement 1 and 2 together
Statement 1 implies that there are more than 2 sessions. Ths, not enough information to draw a conclusion.
Bunuel

(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.
