You can put this solution on YOUR website! .
First, saline solution MAY NOT have a concentration higher than ~ 26% - it becomes saturated and does not dissolve more salt.
so the problem as stated SCARES readers who are familiar with Science.
Second, please do not post more than one problem per post.
