Can some one help explain the concepts to solve Q8 of Henry Park 2010 SA1 Maths Paper 2 :

3/5 of the notes in Mum's safe are $50 notes. 2/3 of the remainder are $10 and $5 notes and the rest are $2 notes. She has twenty four $2 notes. The number of $10 notes is 1/7 of the number of $5 notes. What is the number of $10 notes in Mum's safe?

Thanks a lot!
