Question

let A={×:×is a multiple of 3 less then 25} and B={×:× is a multiple of 6 less than 40} represent in venn diagram and find A-B and B-A

Answer 1

A is multipal of 3
so multiple of 3 are
3,6,9,12,15,18,21,24

[ we take only 24

according to question we take less than 25]
Let multiple of B is 6
and multiple of 6 are
6,12,18,24,30,36, [we take less than 40 ]

total multiple of 3 is 8
and 6 is 6

A=8
B=6

A-B
8-6=2
AND
B-A
6-8=-2
