Maths problem to solve while sitting around the campfire?

[diggit]

June 18

Sorry diggit but not correct

 

[diggit]

Well I know the answer now I think...Not sure if the logic used was fuzzy logic or not

EDITED

I'll withdraw this one as I just realised my initial assumption was wrong.. I'll get back to you later...Hopefully layful:

 

[diggit]

So it can't be May or June as I initially thought, I had things backward. These are months with unique dates, eg 18 and 19 so if she told Alex either 18 or 19 he would know her birthday .

So that leaves July and August.

It can't be the 14th as that would mean two dates were possible.

So it must be the 15,16 or 17 of July/August.

John eventually knows the date so it must be July as August has two possible dates but July has just one...

July 16th? :cake:

 

[BigWave]

Perfectly correct with solid logic.
Well done, and the cigar's on me.
Over to you............

An addition riddle...

Each letter represents a number

Adding top three lines equals fourth line.

Good luck!

This is a real mind bender BW nice one!

One thing I don't get is with the unique dates 18 and 19 why does it exclude the other dates in the month of May or June?

e.g. if Alex was told the 16th he still wouldn't know whether it was in the month of May or July.

Thought you were writing in Irish there for a minute :lol:

U=1. J=5. Y=9

Well done Booney, too easy for bright sparks like you. arty:

FYI there are 2 solutions to this puzzle.

It also works for J=6 So either 1,5,9 or 1,6,9 will solve it.

Your shot :Y:

I have to take the rest of the night off, I've got brain sprain already :lol:

If John had known it was either May or June, then he would have said that Alex may have known the date, because Alex may have been told the 18th or 19th (both of which appear only once).
John knew that Alex didn't know, because he was told either July or August and in each of those months, each other date appears more than once.

Ok , Here is a list of numbers
8 18 11 15 5 4 14 9 19 1 7 17 6 16 - - - - -

What are the 5 missing numbers and in what order should they appear according to the above Patten .

 

[Booney]

Ok , too tricky ? Last chance , has nothing to do with the color , answer given tonight .

Are you looking for the next 5 numbers in the series?
Are the listed numbers in correct order?

Asking for a friend,!

 

[Booney]

Yes mate tell your friend thats correct :lol:
Simple as abc

 

[diggit]

Ok, here's what I got..can work left to right or right to left for the next 5 numbers in the sequence..Booneys numbers are in brackets...not 100% confident on a couple but someone needs to have a crack at it

7 3 13 2 12 (8 18 11 15 5 4 14 9 19 1 7 17 6 16) 10 20 -9 8 18

 

[BigWave]

Missing numbers are:2, 3, 10, 12 and 13.

The correct order is: 10, 13, 3, 12, 2

Very sneaky puzzle :Y:

 

[diggit]

Did you just get a light bulb moment after I posted BW

 

[Booney]

Sorry diggit no prize for you :lol:
Correct BigWave numbers are from 1-19
and placed in alphabetical order . :Y:

 

[BigWave]

No diggit.
It was easier when I figured out it was not an arithmetic sequence.
I'll defer the next puzzle to the next person to figure out the logic.
