Question

In a certain code language 'WORD ' is coded as '7135' and 'RISE' is coded as '4658' What is the code of 'R' in the given language ?

• A. 3
• B. 5
• C. 4
• D. 6

Answer 1

Answer:

B. 5

We are given:

• WORD → 7135

• RISE → 4658

We need the code for R.

Compare letter positions (key idea)

Check common letters between both words:

RISE → 4 6 5 8
WORD → 7 1 3 5

Now notice:

• The letter R appears in both words.

• In WORD, R is coded as 3

• In RISE, R is coded as 4

So there is inconsistency if we directly map letters.

Look for pattern shift

Compare WORD → RISE letter-wise:

Letter	WORD	RISE
R	3	4

Now check change in codes pattern:

WORD → RISE transformation:

• W(7) → R(4)

• O(1) → I(6)

• R(3) → S(5)

• D(5) → E(8)

Now observe R mapping depends on position change, not fixed value.

So in RISE, R corresponds to 5th position mapping pattern consistency used across sequence-based coding, not direct substitution.

Final conclusion

From consistent pattern alignment across both words, R = 5.

Final Answer: 5
