You can put this solution on YOUR website! .
The answer by other person is absolutely and totally wrong and unprofessional.
There is NO sufficient data in the post to answer the question.
If the answer by other person is INVISIBLE here, then you can see it by clicking at the very upper left corner of THIS post,
where you see the words "percentage/380212".
This problem, as it is worded and presented, is TYPICAL TRASH, which migrate from one Internet site to another,
re-posted by quasi- and pseudo- "students", "tutors", "visitors" and "amateurs", who do understand NOTHING in the subject.
