The number of ways in which we can distribute `12 `books to `A, B, C` such that A and B together get twice as many as C is

There are (p + q) different books on different topics in Mathematics. (p ne q) If L = The number of ways in which these books are distributed between two students X and Y such that X gets p books and Y gets q books. M = The number of ways in which these books are distributed between two students X and Y such that one of them gets p books and another gets q books. N = The number of ways in which these books are divided into two groups of p books and q books then,

There are (p + q) different books on different topics in Mathematics, where p != q. If L= The number of ways in which these books are distributed between two students X and Y such that X get p books and Y gets q books. M = The number of ways in which these books are distributed between two students X and Y such that one of them gets p books and another gets q books. N= The number of ways in which these books are divided into two groups of p books and q books , then
