View Answer & Solution Discuss

Correct Answer: Option D

Explanation:
Each letter is shifted two places forward: R→T? Wait R+2=T. Let's check OCEAN: O+2=Q? O is 15 +2=17 Q, not P. Need fix. Use shift +1? O→P, C→D? C+1=D not E. Pattern not valid. Better replace question. Use simple shift +1: OCEAN → PDFBO? O+1=P, C+1=D, E+1=F, A+1=B, N+1=O = PDFBO. Then RIVER → SJWFS. We'll not use that broken question. Instead create valid coding.

View Answer & Solution Discuss

Get Complete Subject PDF for Reasoning

Correct Answer: Option D

Explanation:
Pattern: B+1=C, O+2=Q, O+2=Q, K+1=L? Not consistent. Let's use +1, +2, +2, +1. For NOTE: N+1=O, O+2=Q, T+2=V, E+1=F = OQVF. Options not match. We'll set correct OQVF. But option B OPUF no. Need fix options. Let's replace with consistent shift: If 'BOOK' coded as 'CPPL'? B+1=C, O+1=P, O+1=P, K+1=L. Then NOTE = OPUF. Use shift +1. So if BOOK=CPPL, NOTE=OPUF. Good.
