List of top Analytical Ability Questions on Coding and Decoding asked in AP ECET BSc Mathematics

In a code, the \(r^{\text{th}}\) letter is shifted to the \((27-2r)^{\text{th}}\) letter for \(r = 1, 2, \ldots, 13\). The fourteenth letter is shifted to the \(26^{\text{th}}\) letter, and for \(r = 15, 16, \ldots, 26\), the \(r^{\text{th}}\) letter is shifted to the \((2r-28)^{\text{th}}\) letter. For decoding, the inverse process of the above is followed. Using this coding and decoding, answer the question:

Directions: The number in each question below is to be codified in the following code:

In a code language, \(m^{\text{th}}\) letter is coded as \((m-1)^{\text{th}}\) letter if \(m\) is odd and \((m+1)^{\text{th}}\) letter if \(m\) is even. Then the word that is coded as ‘FZHO’ is
In a code language, \(m^{\text{th}}\) letter is coded as \((m-1)^{\text{th}}\) letter if \(m\) is odd and \((m+1)^{\text{th}}\) letter if \(m\) is even. Then the code word for ‘BUST’ is
In a code language, \(m^{\text{th}}\) letter is coded as \((m-1)^{\text{th}}\) letter if \(m\) is odd and \((m+1)^{\text{th}}\) letter if \(m\) is even. Then the code word for ‘FRAME’ is
