Sep P is the set of even numbers. Set Q is the set of multiples of 3. And R = {x|7 ≤ x < 24, x ∊ N}. The set P∩Q∩R contains some numbers. The sum of these numbers is:

Question

a) 30
b) 54
c) 75
d) 120
e) 165

Answer 1

Set*

Answer 2

Start with R = {x|7 ≤ x < 24, x ∊ N}
R = {7,8,9,10,....,23}
Q = {3,6,9,12,.....}
so Q∩R = {9,12,15,18,21}
2 of those are even, so

P∩Q∩R = {12,18}
now, what is their sum?
