B

#1. We get -

75 = 48 + (swimming pools) - 10 (both patio/swimming pool) + (no patio/swimming pool)
Not sufficient.

#2. We get -

75 = 48 + (swimming pools) - (both patio/swimming pool) + (no patio/swimming pool)
=> 75 = 48 + (swimming pools); since (both patio/swimming pool) = (no patio/swimming pool)
=> swimming pools = 27

#1. We get -

75 = 48 + (swimming pools) - 10 (both patio/swimming pool) + (no patio/swimming pool)
Not sufficient.

#2. We get -

75 = 48 + (swimming pools) - (both patio/swimming pool) + (no patio/swimming pool)
=> 75 = 48 + (swimming pools); since (both patio/swimming pool) = (no patio/swimming pool)=> swimming pools = 27

a = only patio
b = both
c = pool
x = neither

Given:
75 = a + c + x - b
a + b = 48

C1. a = 38, b = 10
75 = 48 - 10 + c - x

C2. b = x
75 = a + c
a + b = 48

so we they say that 48 houses have a patio, it can be represented as a = 48 not a + b = 48.

Nope... a = 48 (Set theory; Union formula)

a = all houses that have patio
b = houses that have both
c = all houses that have swimming pool
x = houses that have neither
