Question

Choose correct answer from the given four options (1-2):
1. If & = {x | x = W, x 12}, A = {x | x is a multiple of 3) and B = (x \x is a multiple
of 4), then An B is
(a) o
(b) {0}
(c) {12}
(d) {0, 12)​

Answer 1

Answer:

{d} {0, 12} is the correct answer

here 0 is a multiple of 3 and 4

and 12 is also a multiple of 3 and 4

so they both are common

So, A n B={0, 12}
