Book Worms (Posted on 2003-02-01) Difficulty: 3 of 5
There were three brothers Albert, Bertrand and Charles.

Albert lent to Bertrand and Charles as many books as they had initially.

After some time Bertrand gave as many books to Albert and Charles as many as they now have.

After sometime Charles did the same thing.

At the end each one of them had 24 books.

Find the books each orginally had.

Let Albert, Bertrand and Charles have initially a, b and c number of books with themselves.

Given that in the first division, Albert gives away to Bertrand and Charles as many books they initially had, so now the number of books each of them have after the first division are:

Albert: (a – b – c); Bertrand: 2b, Charles: 2c

In the second division, Bertrand gives away to Albert and Charles as many books they now have. That is, the number of books they have after the first division, so now the number of books each of them have are:

Albert: 2(a – b – c); Bertrand: (3b – a – c); Charles: 4c

In the third division, Charles gives away to Albert and Bertrand as many books they now have. That is, the number of books they have after the second division, so now the number of books each of them have are:

Albert: 4(a – b – c); Bertrand: 2(3b – a – c); Charles: (6c – a – b)

Now, from the problem, we have:

(a – b – c) = 6 --------(1)

(3b – a – c) = 12 --------(2)

(6c – a – b) = 24 --------(3)

Solving the above three equations, we get: a = 39, b =21 and c =12

So, the number of books each originally had is:

Albert: 39 Books, Bertrand: 21 Books and Charles: 12 Books.
