although the solution to this problem is right but the step is wrong if we delete the node using book's way

as from page 200 part d) deletion of G is the same case as this, the merge process should work as follows: we first merge 37 with its leaf nodes which will form 28 33 37 39 48 then delete 37 from that merged leaf nodes but the steps from the solution is totally different from the book

if you look at the solutions carefully it doesn't follow the book's way. if anyone see this post, please be careful when checking the solutions, because the solutions doesn't follow the book's way. 

Hi! Actually this solution is correct but it just didn't follow this particular book's method. But if you have solved it according to the book and arrived to the same solution then its correct as well. And no marks will be deducted for that.
