If A = { x : x = `3n + 2 , n in N , n le 6}`
B = { x : xis an even number natural number ` 4 , lt x lt 15 `} and
C = { x: x = 3n , `n in N , n lt 8`} then find
(i) `A cup B `
(ii) `A cap B `
(iii) `A cap C ` (iv) `B cap C `
Also find whether the sets A and B : A and C, B and C are disjoint or overlapping sets .
