Question

I know I am going way out on a limb here, but since none of you know where I live, I may be safe.

My alarm system allows me to have a different (3 digit) code based on the day of the week.

The pad has the standard 0-9 keys.

I have sorted the codes numerically, not by the day.

120, 143, XXX, 164, 164, 200, 220

Your task:

Tell me the missing code & the day I use each of the codes.

(yes I know I have two 164s)

If you figure it out, I will change my alarm codes.

It proves that criminals are not as smart as you are.

I think the first digits signify weekday/weekend

but i could be compeletly off.

Is it related to a phone pad/letters?

ok i think i have it:

i have to say, i DID get a lot of help from lil stinker with this. thanks. :)

each letter in the name of the day stands for a number (a=1,b=2,c=3.. etc..)add them together to get the total for each day.

monday:72

tuesday:95

wednesday:100?

thursday:116

friday:63

saturday:109

sunday:84

now convert each of these numbers into base(how many letters there are in its name) (example: tuesday is into base 7 because there are 7 letters in tuesday):)

monday:200

tuesday:164

wednesday:I SEEM TO GET 121 FOR THIS :/ THIS COULD BE MY MISTAKE BUT COULD IT POSSIBLY BE A TYPO??

thursday:164

friday:143

saturday:155

sunday:220

so, anyway,..

120 - wednesday??

143 - friday

155 - saturday

164 - thursday

164 - tuesday

200 - monday

220 - sunday
