This was going to be part of a challenge cache series, but there is a moratorium on challenge caches, so this is now a proper puzzle in the same theme. The cache is not located at the published co-ordinates.
To find the co-ordinates for the final location, complete the following puzzle.
Silly Security Solutions offers several high-quality sirens for sale. Match each siren to its price, loudness (in decibels) and the year it was first put on the market using the information below.
1. The $188 siren is 5 decibels quieter than the Eco Alert.
2. The Eco Alert is 105 decibels loud.
3. Neither the siren released in 1996 nor the Viking 5 is the siren with a loudness of 115 decibels.
4. The Eco Alert is either the siren released in 2000 or the $145 siren.
5. The siren with a loudness of 110 decibels doesn't cost $182.
6. The siren released in 1999 is 5 decibels louder than the Bradley X9.
7. Of the $145 siren and the siren with a loudness of 100 decibels, one was released in 1996 and the other is the Viking 5.
8. The siren with a loudness of 110 decibels is either the siren released in 2009 or the Eco Alert.
The following grid may assist you in solving this puzzle:
The cache can be found at S41 10.ABC E174 54.DEF, where:
A = the year the Viking 5 was released - the year the Securalert was released
B = the second digit in the price of the Eco Alert
C = the price of the Bradley X9 - the price of the Viking 5
D = (the price of the Eco Alert - the decibels of the Securalert)/10
E = (the decibels of the Securalert - the decibels of the Viking 5) - (the year the Bradley X9 was released - the year the Securalert was released)
F = The first digit of the year the Viking5 was released
