Basically, each letter was coded with a digit from 1 to 9, where 1 to 8 each coded three different letters, and 9 coded only two letters, for a total of 26 letters. The given sentence was coded using such digits. Now, look for common letters between two words; for example, "the" and "weary". "the" was coded as 278 and "weary" as 23559. E is common in both. In the digit code, look for the common numbers: only 2 is common between the two, so E must be 2. Similarly,you need to look for common alphabets in two words and then their codes, if a digit is repeating twice in a code and no alphabet is repeating that means there are two alphabets with the same digit code.
