x theatre patrons
y theatre patrons were late
.05(x)= theatre patrons who were late and were seated immediately.
.30(y)= theatre patrons who were late and who weren't seated until the end of the first act.
.70(y)= theatre patrons who were late and were seated immediately.
y/x=?
.70(y)=.05(x)
y/x=.05/.7~ 7 % B

Another way of doing this:
let the total theater patrons = 100
5% of total theater patrons who were late and seated immediately = 5
patrons who were late = x
30% of those who were late (x) were not seated immediately = .30(x)
total late = 5 + .3x = x
5 = (7/10)*x
x = 50/7 ~ 7
the total number of patrons who were late = 7%
let the total theater patrons = 100
5% of total theater patrons who were late and seated immediately = 5
patrons who were late = x
30% of those who were late (x) were not seated immediately = .30(x)
total late = 5 + .3x = x
5 = (7/10)*x
x = 50/7 ~ 7
the total number of patrons who were late = 7%

"5% of the theatre patrons are late and are seated immediately"
"30% of the patrons who are late are not seated until the end of the first act."
please explain what am I missing here.
first line says 5% of the total number of patron are late and are seated immediately
2nd line says 30 % of patron who are late are not seated immediately. how is that possible. ? the patron who are late are seated immediately according to the first statement.
"30% of the patrons who are late are not seated until the end of the first act."

Isn't this is set theory problem?
5% is X and Y
30% is X but not Y
5% is X and Y
30% is X but not Y
