How smart is /sci/?

Assume the following sets:
U = {x : x ∈ N, x ≤ 99}
A = {x : x ∈ U, x mod 5 = 0}
B = {x : x ∈ U, 3x mod 2 = 0}
C = {x : x ∈ U, 20 < x < 40}
What are the elements of A ∩ B ∩ C? Use commas to separate elements in your answer.

I didn't take Latin in school. I can't help you op.

>>1
smart enough to know you are a faggpt

>>1 Combine A and B and you get that x mod 10 = 0. Combine that with C and you get A ∩ B ∩ C = {30}

Meh!
