How many ways are there to make 20p using 1p 2p 5p 10p and 20p coins?
40 ways.
How many ways to make 50P using 50P 20P 10P 5P 2P and 1P coins?
To find the number of ways to make 50p using the given coins, we can use a technique called dynamic programming. We can create an array of size 51 to store the number of ways to make each value from 0 to 50p. We initialize the first element as 1 (since there is one way to make 0p), and then iterate through each coin denomination, updating the array based on the current coin value. Finally, the value at index 50 of the array will give us the total number of ways to make 50p using the given coins.
