Question

If in certain code, 'Clever' is written as 'XOVEVI', then 'Smart' will be written as.........

• A. HZNGI
• B. HNZIG
• C. GHNGI
• D. GIHZN

Hint:

A quick way to remember opposite letter pairs is that their standard position numbers add up to 27 (e.g., C(3) + X(24) = 27). This is a very common type of code in reasoning tests.

Answer 1

The Correct Option is B

This is a substitution cipher problem. We need to find the rule that transforms 'Clever' into 'XOVEVI'. Step 1: Analyze the relationship between the letters. Let's write the letters of the alphabet and their reverse pairs: A B C D E F G H I J K L M Z Y X W V U T S R Q P O N Now let's map the original word to the coded word:
C \(\rightarrow\) X (C is the 3rd letter from the start, X is the 3rd letter from the end)
L \(\rightarrow\) O (L is the 12th from the start, O is the 12th from the end)
E \(\rightarrow\) V (E is the 5th from the start, V is the 5th from the end)
V \(\rightarrow\) E
E \(\rightarrow\) V
R \(\rightarrow\) I (R is the 18th from the start, I is the 18th from the end) The rule is: Each letter is replaced by its opposite letter in the alphabet.

Step 2: Apply the rule to the word 'Smart'. We will find the opposite letter for each letter in 'Smart'.
S \(\rightarrow\) The opposite of S is H.
M \(\rightarrow\) The opposite of M is N.
A \(\rightarrow\) The opposite of A is Z.
R \(\rightarrow\) The opposite of R is I.
T \(\rightarrow\) The opposite of T is G.

Step 3: Form the final coded word. Combining the opposite letters, we get HNZIG.
