Maths Mate Sheet 6 Question 23 (Term 3 2014)
Prediction:I predict this problem will be about coding, because of the strange symbols.
Read: An archeologist found some ancient numbers written as follows: (I’ll use keyboard symbols instead)
$$£ for 33. $€€€ for 28. And €££ for 6. What did $€€£ equal?
Clarification: None needed.
The Big Question: What did $€€£ equal?
Mathematician’s Toolbox: Look for a pattern/Test all possibilities
Solving: First I tried to use the first clue to work out what $ means. After I’d tried many ways I came up with 16 = $ and 1 = £. I then skipped the second clue and went onto the third. Since I know £ is one I take away two from six which is 4, so that’s what € is. Now we’ll add the amounts up. 16 + 4 + 4 + 1 = 25.
Conclusion: So the answer was 25.
