Rows of coins

Take five coins: 1p, 2p, 5p, 10p, 20p and put them in a row using these clues.
The total of the first three coins is 27p.
The total of the last three coins is 31p.
The last coin is double the value of the first coin. 

Now take six coins: two 1p, two 2p, two 5p and put them in a row using these clues.
Between the two 1p coins there is one coin. 
Between the two 2p coins there are two coins. 
Between the two 5p coins there are three coins. 
What if you take two 10p coins as well, and between them are four coins?

    The first questions answer is 20p 5p 2p and if you add them together it will equal 27p and the second one is 10p 20p 1p and the third one is 1p=2p 5p=10p 10p=20p
