The Weekly Warlock Wind-Up: Spare change (answer)

This week I gave you this small little puzzle:

In your pocket, you have £6.30. It is made up of four different denominations of coins, and the largest denomination is £1. There is exactly the same number of coins. How many of each coin is there and what are their values?

The small little answer can be seen after the break!

Well, unless there’s a fancy algebraic method, the only real way to work this one out was with some educated guesses and good old trial and error. Eventually, you should hopefully have come up with the following solution:

  • 5 x £1
  • 5 x 20p
  • 5 x 5p
  • 5 x 1p

No puzzle next week because I’m away, so I’ll see you in two weeks time for the next Wind-Up!

Vel.

    I solved this one by writing out the pence values of each coin if there were 1, 2, 3, etc of them. I then eyeballed the list to see which ones four numbers would add up to 630.
