My method of solution will be to re-tell the same story in more short sentences, to make their meaning absolutely clear to you.


(a)  Lilly is 8 years now and she is 5 years older than her brother.
     How old is Lilly brother ?


     In this form, even a kindergarten alumni can answer the question.



(b)  Lilly is 8 years now and she is half as old as her sister.
     How old is Lilly sister ?


     This time I am not sure about a kindergarten alumni.

     But a 2-nd grade student definitely can solve it on his (or her) own, without any help from outside.

It is exceptionally powerful and reliable method of solution to separate long twisted sentences in more short and clear parts.

Learn and MEMORIZE it from my post.
