How many ways to make 20p usin 1p 2p 5p AND 10Pcoins?

Answer 1

To find the number of ways to make 20p using 1p, 2p, 5p, and 10p coins, we can use a combinatorial approach or dynamic programming. The exact calculation can get complex, but generally, you would iterate through each coin denomination and calculate combinations. Using the generating functions or coin change algorithms, it can be shown that there are 42 distinct ways to make 20p with these coins.
