Correct Answer & Explanation
Option C
• The pattern followed is: +1, -1, +1, -1, +1 for consecutive letters.
• Z (+1) → A
• E (-1) → D (not Y as in question, let's re-evaluate the pattern for 'ZEBRA' to 'AYCSB')
• Let's re-examine 'ZEBRA' to 'AYCSB':
• Z (+1) → A
• E (-4) → A (This is not a simple +1/-1 pattern)
• B (+1) → C
• R (+1) → S
• A (+1) → B
• The question's example 'ZEBRA' to 'AYCSB' seems to have a typo or a more complex pattern. Let's assume a simpler, more common pattern for medium level which is usually consistent. If ZEBRA -> AYCSB, this is a mixed pattern: Z(+1)=A, E(-4)=A, B(+1)=C, R(+1)=S, A(+1)=B. This is highly inconsistent. Let's assume the question meant a consistent pattern like +1, +1, +1, +1, +1 or +1, -1, +1, -1, +1. Given the options, let's try a common alternating pattern.
• Let's assume the pattern is +1, -1, +1, -1, +1 for 'ZEBRA' to 'AYCSB'.
• Z (+1) → A
• E (-1) → D (This doesn't match 'Y')
• Let's consider a different interpretation of 'AYCSB'. It might be a typo in the question or a very complex pattern. For a medium level question, a more straightforward pattern is expected.
• Let's consider a common pattern: Each letter moves forward by one position.
• Z (+1) → A
• E (+1) → F
• B (+1) → C
• R (+1) → S
• A (+1) → B
• If 'ZEBRA' was 'AFCSB', then 'TIGER' would be 'UJHFS'. This matches option C, assuming the example 'AYCSB' had a typo and should have been 'AFCSB'.
• Let's re-evaluate the given example 'ZEBRA' is coded as 'AYCSB'.
• Z → A (+1)
• E → Y (-6)
• B → C (+1)
• R → S (+1)
• A → B (+1)
• This mixed pattern is unusual for a medium level and specific. Let's assume the most common pattern for this type of question which is a uniform shift or alternating uniform shift.
• Let's try the pattern of shifting each letter forward by one position (as in the previous question example, which is very common).
• T (+1) → U
• I (+1) → J
• G (+1) → H
• E (+1) → F
• R (+1) → S
• This gives 'UJHFS'. This is a plausible answer and matches option C. The example 'ZEBRA' to 'AYCSB' might be misleading or incorrect for a standard pattern, or it implies a very specific non-uniform shift which is rare for 'medium' level. Given the options, a consistent +1 shift is the most logical choice if we assume the example intended a simple shift or had a typo.
