(1) 30% of members take both types of classes.
(2) 40% of members take only spin classes.
OE to follow...!!!
Since its a percentage question so to make things easy lets take the total number of members of health club is 100 STAT1 30% of members take both types of classes => 30 people take both types of classes Since everyone takes atleast one type of class. So, People taking only Yoga + People taking only health class + people taking both type of classes = 100 SO, people who take only Yoga + people who take only health class = 100 - 30 = 70 So, NOT SUFFICIENT
STAT2 40% of members take only spin class => 40 people Since everyone takes atleast one type of class So, People taking only Yoga + People taking only health class + people taking both type of classes = 100 So, People taking only health + people taking both type of classes = 100 - 40 = 60 People taking only health + people taking both health and yoga = people taking health class in total = 60 So, SUFFICIENT
So, Answer will be B Hope it helps!

Here's a step-by-step approach using the Double Matrix method.
Here, we have a population of health club members, and the two characteristics are: - taking yoga or not taking yoga - taking spin classes or not taking spin classes
So, we can set up our diagram as follows: IMPORTANT: Notice that I placed a zero in the bottom right corner because we are told that all club members take at least one type of class In other words, there are zero members who take neither yoga nor spin classes.
Also notice that I made the total population of club members = 100. This is okay since the target question asks us to find a certain PERCENT.
Target question:What percent of members take yoga classes?
In other words, we want to find the sum of the top two boxes.
Statement 1: 30% of members take both types of classes. So, we can place 30 of the 100 members in the top-left box. Does this provide enough information to find the sum of the top two boxes? No. Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: 40% of members take only spin classes. So, we can place a 40 in the bottom left box.
This means that a total of 40 of the 100 members do NOT take yoga.
From this, we can conclude that the remaining 60 members DO take yoga. In other words, 60% of the members take yoga. Since we can answer the target question with certainty, statement 2 is SUFFICIENT

Prompt analysis There are yoga class and spin class. There are members who either joins spin or yoga or both classes. That means 100 = N(y only) + N(s only) + N(y and s) Superset The value of percentage of member will be in the range of 0-100%
Translation In order to find the exact value, we need: 1# the exact percentage of people taking yoga classes 2# The rest of the parameter in in the prompt analysis
Statement analysis St 1: N(y and s) = 30. Therefore N(y only) +N (s only) = 70. Cannot say anything about the rest two variable. INSUFFICIENT St 2: N(s only) = 40 .therefore N(y only) +N(y and s) = 60. Cannot say anything about the rest two variable. INSUFFICIENT
St 1 & St 2: N(y and s) = 30 and N(s only) = 40. Therefore N(y only) = 30. ANSWER. Option C

Since number of people who take neither = 0 (Given:all club members take at least one type of class), then we need to find members who take Yoga
40% of members take only spin classes--> remaining 60 % take yoga classes (i.e. those members who take yoga only + those members who take both yoga and spin =60%)
