GRAPE MA QLMVFGCB, BLLCRQU XRUX GPMRQUB, TFQBMPQMEK BTXLYNEL DLBM BXFVB PUPRQBM LPTX FMXLG CAN SUMONE HELP SOLVE THIS CIPHER TEXT ABOVE PLEASE IM SO LOST

OpenStudy (amistre64):

if its a quipto crypt .... it may be possible. in other words, if one letter is simply a substitute for another letter, then the way words are formed give us clues about what the possibilities are. other than that its pretty vague

OpenStudy (amistre64):

the most common letters used in english are r,s,t,l,n and the vowel e

OpenStudy (anonymous):

I'm lost on what letters to plug In where and the book isn't helping much at all

OpenStudy (amistre64):

we have a four letter word that has the same letter at the start and end; lets try the word "that" that GRAPE MA QLMVFGCB, BLLCRQU XRUX GPMRQUB, TFQBMPQMEK BTXLYNEL DLBM BXFVB PUPRQBM LPTX FMXLG let x=t, r=h, u=a h h a that h a GRAPE MA QLMVFGCB, BLLCRQU XRUX GPMRQUB, t t a h t t TFQBMPQMEK BTXLYNEL DLBM BXFVB PUPRQBM LPTX FMXLG

OpenStudy (amistre64):

any clues, and what type of book?

OpenStudy (anonymous):

Its an e book it gave me a clue that b represents ss

OpenStudy (amistre64):

the formating in here doesnt equally space letters, but this is what i get for teh frequency of each BBBBBBBBB MMMMMMMM LLLLLLLL XXXXXX QQQQQQ PPPPPP RRRRR GGGG UUUU FFFF TTT EEE CC AA VV K Y N D V

OpenStudy (anonymous):

Do I count the numbers or multiply them by different numbers

OpenStudy (amistre64):

well, if your book covers the frequency of letter usage in words, this looks like a number theory thing ... at least it was part of codes in the class i took h s s h a that h as GRAPE MA QLMVFGCB, BLLCRQU XRUX GPMRQUB, s s t s st s a h s t t TFQBMPQMEK BTXLYNEL DLBM BXFVB PUPRQBM LPTX FMXLG

OpenStudy (amistre64):

http://www.math.cornell.edu/~mec/2003-2004/cryptography/subs/frequencies.html here is a letter frequency table

OpenStudy (anonymous):

It doesn't speak on frequency the text I have here just touches bases on simple and modular codes

OpenStudy (anonymous):

This is the only key given

OpenStudy (amistre64):

it seems to use the same thoughts i did ... can you post the actual cipher question as well? just to make sure theres no mistakes in it

OpenStudy (anonymous):

Sorry about my little doodles on it

OpenStudy (amistre64):

one thing to note is that your note being consistent in your decipher. fill out each letter completely; every X = T, every B = S .... you have a d=h for some reason, and you have an L=E , which i spose is a good enough guess

OpenStudy (amistre64):

S__ an E does make the most sense to me, or O SOO_H__

OpenStudy (amistre64):

yeah, its a pain ....

OpenStudy (anonymous):

Does every letter have its own wordword

OpenStudy (anonymous):

Letter I mean
