Question

H L X R Z O H X R V M X V = _____________________________

Fill in the Blanks

Solution

SOCIAL SCIENCE

Explanation;

Hint:

For this question, we need to use the Atbash cipher. For Atbash cipher, first we write the alphabets from A to Z and then in reverse from Z to A below that.
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

Now to solve, we look up the corresponding letter from the table to replace in code to get the actual word.

So, for H L X R Z O H X R V M X V, from the table,

for H, it is S

for L, it is O

for X, it is C

for R, it is I

for Z, it is A

for O, it is L

for H, it is S

for X, it is C

for R, it is I

for V, it is E

for M, it is N

for X, it is C

for V, it is E

So, the actual word is SOCIAL SCIENCE
