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.
We need to figure out if Y > S is just TRUE or FALSE, where Y is the members who attended yoga and S is the members who attended strength training.
Statement 1:
Every member of the yoga group attends one other training, but we are not sure if it is strength training or some other training, so it is not sufficient.
Statement 2:
Every member of the yoga group is in the strength training group-
This implies that either both the groups have an equal number of members or strength is gonna have more members, i.e. Y ≤ S.
Thus we can definitely say that Y>S is FALSE.
Therefore, it is B, only statement 2 is required, and statement 1 alone is not sufficient.
