Question
If NOIDA is coded as OPJEB, how is DELHI coded?
Options
- EFMIJ
- EFMIH
- EFLIJ
- DFMIJ
Show the answer and the worked solution
Correct answer: A. EFMIJ
Worked solution
- The shift is +1.
- D→E, E→F, L→M, H→I, I→J.
- The code is EFMIJ.
Answer: EFMIJ.
The idea
Same rule, different word. Practising the +1 and −1 codes until they are automatic frees time for the harder items.
Shortcut. The options differ at the first (D or E), third (L or M) and last (H or J) letters. D+1 = E, L+1 = M and I+1 = J give EFMIJ.
Common trap. "EFMIH" — shifting the final I backwards to H; every letter in NOIDA → OPJEB moves forward, so I becomes J.
