|A∪B|=|A|+|B|−|A∩B|

No. of numbers between 1 and 200 divisible by 7 (setA)

=⌊2007⌋

=28

No. of numbers between 1 and 200 divisible by 11 (setB)

=⌊20011⌋

=18

No. of numbers between 1 and 200 divisible byLCM(7,11)(set{A∩B})

=⌊20077⌋

=2

therefore

|A∪B|=28+18−2=44

hope it helps please mark this as brainliest.
