Maths Mate Sheet 8 Question 23 (Term 3 2014)

Prediction: I predict this problem will be about patterns.

Read: An archeologist found some ancient numbers written as follows: (I’ll use keyboard symbols instead).

!!## For 52. !@@@ For 40. And @@### For 13. What did !@### equal?

Clarification: None needed.

The Big Question: What did !@### equal?

Mathematician’s Toolbox: Have I seen a similar problem?/Test all Possibilities

Solving: First I used the first clue to figure out what  is ! and #. I evened it and got the following results !=25 and #=1. After that I used the second clue by taking away 25 from the total and was left with 15 then I divided that by 3 because there were 3 symbols and got @=5. Then I added them all up: 25 + 5 + 1 + 1 + 1 = 33.

Conclusion: So the answer was 33.
