Question

In a certain code, ``SHRIJEET'' is written as ``QFPGHCCR''. How is ``INTEREST'' written in that code?

• A. GLRCPCQR
• B. BWKXUAA
• C. GYQQGML
• D. SHXXHLH
• E. GWPPNCV

Hint:

To solve these quickly without counting on fingers, use the "EJOTY" (5, 10, 15, 20, 25) method to anchor alphabetical positions. Also, if you find the first 2-3 letters match only one option, you can select it immediately and save time!

Answer 1

The Correct Option is A

Concept:
In letter-to-letter coding, each letter of the original word is shifted forward or backward in the alphabet by a certain number of positions. We determine the "key" by comparing the alphabetical positions of each corresponding letter.

Step 1: Determine the coding pattern from ``SHRIJEET''.
Let's look at the numerical positions ($A=1, B=2, \dots$):
• S (19) $\to$ Q (17) : $-2$
• H (8) $\to$ F (6) : $-2$
• R (18) $\to$ P (16) : $-2$
• I (9) $\to$ G (7) : $-2$
• J (10) $\to$ H (8) : $-2$
• E (5) $\to$ C (3) : $-2$
• E (5) $\to$ C (3) : $-2$
• T (20) $\to$ R (18) : $-2$ The pattern is a constant shift of $-2$ for every letter.


Step 2: Apply the $-2$ shift to ``INTEREST''.
• I (9) $- 2 = 7 \to$ G
• N (14) $- 2 = 12 \to$ L
• T (20) $- 2 = 18 \to$ R
• E (5) $- 2 = 3 \to$ C
• R (18) $- 2 = 16 \to$ P
• E (5) $- 2 = 3 \to$ C
• S (19) $- 2 = 17 \to$ Q
• T (20) $- 2 = 18 \to$ R The resulting code is GLRCPCQR.
