Question

If in a certain code language $ABCD$ is written as $ZYXW$, then how is the word$DANCE$ written in that code?

Answer 1

Find the required code:

Alphabet	Forward Ranking	Backward Ranking
$A$	$1$	$26$
$B$	$2$	$25$
$C$	$3$	$24$
$D$	$4$	$23$
$E$	$5$	$22$
$F$	$6$	$21$
$G$	$7$	$20$
$H$	$8$	$19$
$I$	$9$	$18$
$J$	$10$	$17$
$K$	$11$	$16$
$L$	$12$	$15$
$M$	$13$	$14$
$N$	$14$	$13$
$O$	$15$	$12$
$P$	$16$	$11$
$Q$	$17$	$10$
$R$	$18$	$9$
$S$	$19$	$8$
$T$	$20$	$7$
$U$	$21$	$6$
$V$	$22$	$5$
$W$	$23$	$4$
$X$	$24$	$3$
$Y$	$25$	$2$
$Z$	$26$	$1$

$$\begin{gathered} \therefore \stackrel{1}{A}\stackrel{2}{B}\stackrel{3}{C}\stackrel{4}{D}\stackrel{BackwardRankingAlphabet}{\to }\stackrel{1}{Z}\stackrel{2}{Y}\stackrel{3}{X}\stackrel{4}{W} \\ \stackrel{4}{\Rightarrow D}\stackrel{1}{A}\stackrel{14}{N}\stackrel{3}{C}\stackrel{5}{E}\stackrel{BackwardRankingAlphabet}{\to }\stackrel{4}{W}\stackrel{1}{Z}\stackrel{14}{M}\stackrel{3}{X}\stackrel{5}{V} \end{gathered}$$

Hence required code for $DANCE$ is $WZMXV$.
