You’ll encounter different types of coding-decoding questions in mocks, so try to understand the different patterns and methods that can be used. You never know which technique will help you in the actual exam. :)
If a question has a complicated logical chain like this one, you can try using option elimination instead of figuring out the entire pattern.
Like for this one you can go with the letters, for which simply find the sum (given in the third column) and identify which letter it corresponds to by counting through the alphabet repeatedly. Since there are only 26 letters, after Z, start again from A. For example, 57 ÷ 26 leaves a remainder of 5, so the corresponding letter is E. Similarly, 78 leaves a remainder of 0, which corresponds to Z.
So only option 3 fits in!
