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 2} B = {x : x is a multiple of 5}, then A-B is

If A={x:x is a multiple of 3} and B={x:x is multiple of 5} 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

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_______

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

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

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
