Let X = {x : 1 le x le 50, x in N} A = {x: x is multiple of 2} B = {x: x is multiple of 7} Then find number of elements in the smallest subset of X which contain elements of both A and B

If A={x:x is a multiple of 3) and,B={x:x is a multiple of }, then A-B is

if A ={x:x is a multiple of 3 } and , B={x:x is a multiple of 5 }, then A-B is

Let X = {n in N :1 le n le 50} . If A = {n in X: " n is a multiple of 2 "} and B= {n in X: " n is a multiple of 7"} , then the number of elements in the largest subset of X containing neither an element of A nor an element of B is_______

If A = {x:x is a multiple of 4} and B= {x:x is multiple of 6} then A sub B consists of all multiples of

Let A = {x : x is a multiple of 3} and B = {x : x is a multiple of 5), then A nn B is given by

If A = {x : x is a multiple of 4} and B = {x : x is a multiple of 6}, then A sub B consists of all multiple of

Let A= {x: is a multiple of 3 } and B= { x:x is a multiple of 5} then A cap B is given by

If A={x:x is a multiple of 4} and B={x;x is a multiple of 6} then A nn B has the multiple of

if A={x:x is multiple of 4} and B= {x:x is a multiple of 6}, then A cap B consists of multiples of
