Question

If in a code language, “PAPER” is written as “QBQFS”, then “MANGO” is written as:

• A. NBOHP
• B. NBNHP
• C. NBOGP
• D. NBPHO

Hint:

When a pattern is a simple $+1$ shift, you don't need to write out every step! Just look at the first and last letters of your word: M goes to N, and O goes to P. Looking at the options, only (a) starts with N and ends with P!

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Letter coding puzzles involve shifting letters according to a specific alphabet pattern. We can determine the rule used by matching each letter of the original word with the letter in the corresponding position of the coded word.

Step 2: Key Formula or Approach:
Examine the forward shifting pattern of the letters: $$\text{Letter}_{\text{Coded}} = \text{Letter}_{\text{Original}} + n$$ Find the value of the shifts ($n$) for each letter position, then apply this exact rule to decode the target word.

Step 3: Detailed Explanation:
Let's look at the relationship between the letters in the example PAPER $\rightarrow$ QBQFS: $\text{P} \xrightarrow{+1} \text{Q}$ $\text{A} \xrightarrow{+1} \text{B}$ $\text{P} \xrightarrow{+1} \text{Q}$ $\text{E} \xrightarrow{+1} \text{F}$ $\text{R} \xrightarrow{+1} \text{S}$ The pattern shows that every letter shifts forward by exactly 1 position in the alphabet ($+1$ shift). Now, apply this identical $+1$ rule to each letter of the word MANGO: $\text{M} \xrightarrow{+1} \text{N}$ $\text{A} \xrightarrow{+1} \text{B}$ $\text{N} \xrightarrow{+1} \text{O}$ $\text{G} \xrightarrow{+1} \text{H}$ $\text{O} \xrightarrow{+1} \text{P}$ Putting the shifted letters together gives the coded word NBOHP, which matches option (a).

Step 4: Final Answer:
"MANGO" is written as NBOHP.
