1.	If `A xx B = {(p, q), (p, r), (m, q), (m, r)}`, Find `A` and `B`
Answer» We are given, `AxxB = {(p,q),(p,r),(m,q),(m,r)}` Here, `A` is the set of all first elements i.e `A = {p, m}` (As first element contains only p and m). `B` is the set of all second elements i.e. `B = {q, r}` (As second element contains only `q` and `r`).
