If A and B are two sets such that `n(A)=115 ,\ n(B)=326 ,\ n(A-B)=47` , then write `n(AuuB)dot`

If A and B are two sets such that n(A)=115,n(B)=326,n(A-B)=47 then write n(A uu B)

If A and B are two sets such that n(A) =20 , n(B) =25 and n(AcapB) =5 , then write n(AuuB) .

If A and B are two sets such that n(A)=20,n(B)=24 and n(A uu B)=40 then write n(A nn B)

If A and B are two sets such that n(A) =23, n(B)=37 and n(A - B) =8 then find n(Acup B) .

A and B two sets such that n(A)=3 and n(B)=6 , then

If A and B are two sets such that n(A) =8, n(B)=11 and n(A cup B) =14 then find n(Acap B) .

If A and B are two sets such that n(A) =54,n(B) =39and n (B-A)=13 then find n( Acup B) .

If A and B are two sets such that n(A)=30, n(B)=26 and n(A cup B)=50, then find (i) n(A-B) (ii) n(A cap B)

If A and B are two sets such that n(A) = 17,n(B)=23 and n(A cup B) = 38 , then find n(A cap B) .
