Have a look at this thread: http://www.elevenplusexams.co.uk/forum/ ... hp?t=21610" onclick="window.open(this.href);return false;
and then see if you can work it out.

Re: maths
I am not impressed by this question as it assumes Library B has 0 books. The answer will be different depending on the number of books Library B has. Just wondering which book is it from?
Word problems can be mastered by practising over and over for variety of types. See Bond Assessment Book 1 & Book 2 for 11-12, 12-13 etc.

Re: maths
I may be having a bad evening maths-wise, but whatever numbers of books for Library A and Library B I start with I still end up with a difference of 45 books once the 11 have been moved, as in the answer...parent2013 wrote:I am not impressed by this question as it assumes Library B has 0 books.

Re: maths
Yes. The number each library has to start with does not matter so long as the library with more books has 67 or greater. 67 - 22 equals 45.
When you move one item from one pile to another you change the difference between the two piles by 2.
