There are a total of x members.
y members use the pool.
.30(x)= Use both the pool and sauna
.40(y)= Use only pool
.60(y)= Use both the pool and sauna
We want what how many of the x members use the pool, so technically, we want y/x.
.60(y)=.30(x)
y/x=.30/.60=1/2
1/2*100= 50%

I am actually confused with the above. I started off with the below equation:.30(x)= Use both the pool and sauna
.60(y)= Use both the pool and sauna
P + S - B = 100
Based on the details in the question; P - B = 40; and B = 30, then P = 70. I guess I am missing something here.
