58. I is 3 letters away from L, L is 4 letters away from P, therefore we can guess that the letter we require is 5 letters away from P. U is the letter that is 5 away from P. We can test it by examining the rest of the letters. A should be 6 letters away from U. It is. Finally, H is 7 letters away from A, confirming the answer as U.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z


Here we see that G is the 7th letter of the alphabet. T, it’s corresponding letter in code, is the 7th letter from the end of the alphabet. Similarly H is the 8th letter of the alphabet while R, this time, is 9th letter from the end of the alphabet. O is the 15th letter of the alphabet and L is the 15th from the end of the alphabet. S is the 19th letter of the alphabet and G is the 20th letter from the end of the alphabet. T is the 20th letter of the alphabet and G is the 20th letter from the end of the alphabet.

Now, we can assume that the code works like this, for the 1st 3rd 5th etc. number, the code is like this:

A  B  C  D  E  F  G   H  I   J   K   L  M N  O  P Q R S T U V W X Y Z
Z  Y  X  W  V  U  T  S  R  Q  P  O  N  M  L  K  J  I  H  G  F  E  D  C  B  A

Therefore, the first P and the M in PUMP, become a K and N.

Then, we see that  for the 2nd 4th 6th etc. letters, they follow this code:

A  B  C  D  E  F  G   H  I   J   K   L  M N  O  P Q R  S  T  U V  W X   Y Z
Y  X  W  V  U  T  S  R  Q  P  O  N  M  L  K  J  I  H  G  F  E  D  C  B  A Z

Here we learn that the U and second P become E and J respectively.

Therefore PUMP becomes KENJ

不妨事,大家都是这么过去的。

我感觉第二题只有把每个字母的地位带进去就能发现，他们的法则是加起来的和是27，26循环的，所以PUMP也是这个法则，所以是C
