Note: In a certain code, $n^{th}$ letter of the English alphabet is called as $r^{th}$. where n+12 =26m+r such that m and r are integers and 0 ≤ r ≤ 25 and when r=0. $r^{th}$ letter is treated as ‘z ’. For example the 5th letter E is coded as $17^{th}$ letter Q. N as Z and R is coded as D. The reverse process is used for decoding. Use these to answer questions
