Hint
Remember that you have the same number of each coin.
Answer
134 of each coin.
Reasoning
We have equal numbers of 2p, 5p, 10p, and 20p.
And 2p + 5p + 10p + 20p = 37p.
There are 134 lots of 37p in £49.58.
Double-Checking
134 x 37 = 4958.
Puzzle 531
Assign every letter of the alphabet its numerical value: A=1, B=2, C=3, and so on, up to Z=26.
Can you find any common 6-letter words that have a total over 115?
For example, WIZARD = 23 + 9 + 26 + 1 + 18 + 4 = 81.
