Question

Let A={ x: x€N, x is a
multiple of 2} B={ x: x€N,
x is a multiple of 5) C={ x:
x€N,x is a multiple of 10}
. Then AU(B nC) ie A
union B intersection C is?
​

Answer 1

Answer:

A=(2,4,6,8...)

B=(5,10,15...)

c=(10,20,30...)

b intersect c = (10,20,30...)

au(b intersect c)=(2,4,6,8,10,12,14,16,18,20....)
