In a certain code, RUPEE is written as SWSIJ. Using the same rule, how will LEDGER be written?
The code moves the first letter forward by one place, the second by two, the third by three, and so on. Applying shifts of 1 to 6 to LEDGER gives MGGKJX. A uniform shift of one place would give MFEHFS, which does not match the pattern shown by RUPEE.
- AMGGKJXCorrect
- BMFEHFS
- CMGGKIX
- DLGGKJX
Explanation
Compare RUPEE with SWSIJ: the letters move forward by 1, 2, 3, 4 and 5 places respectively. Applying shifts 1 to 6 to L, E, D, G, E, R gives M, G, G, K, J, X. Option MFEHFS wrongly shifts every letter by just one place.
