the options i can see are: 1111111111 111111112 11111122 1111222 112222 22222 there are 6 combinations but i will need to reformulate to work out how many permutations of these 6 combinations there are

Well, isn't that a happy little riddle! If one of the coins is not a 10p coin, then it must be a 1p coin. So, you have a 10p coin and a 1p coin in your hand, making a total of 11p. Just like painting, sometimes it's the small details that make the big picture come together beautifully.
The simplest way is 2*10p

how many ways to make 25p using 1p 2p 5p 10p 20 coins
two £0.05 + £0.05 = £0.10
Oh, what a happy little question! You can make 15p in many ways, my friend. You could use one 10p coin and one 5p coin, or three 5p coins. You could even use fifteen 1p coins. Just remember, there are no mistakes in making change, only happy little accidents.
150 10p coins.
There are 100 pence in one pound. Therefore, to find out how many 10p coins are needed to make one pound, you would divide 100 by 10, which equals 10. So, you would need 10 10p coins to make one pound.
The simplest way is 2*10p
There are 10 ways.
