Difficulty: Hard
Correct Answer: BYOUYCAN
Explanation:
Introduction / Context:
This problem tests letter rearrangement coding-decoding. The letters are not shifted in the alphabet; instead, they are moved to different positions to form the coded output. The example EXAMPLES → EMAXSEPL reveals a consistent positional permutation that must be applied to BUOYANCY.
Given Data / Assumptions:
Concept / Approach:
Label letters of EXAMPLES by position 1 to 8, and then map which original positions appear in the coded word. Once the position order is discovered, apply that same order to BUOYANCY (also 8 letters).
Step-by-Step Solution:
Write EXAMPLES with positions:
1E 2X 3A 4M 5P 6L 7E 8S
Coded word: E M A X S E P L
Match each coded letter to its original position:
E comes from position 1
M comes from position 4
A comes from position 3
X comes from position 2
S comes from position 8
E comes from position 7
P comes from position 5
L comes from position 6
So the position order is: 1,4,3,2,8,7,5,6.
Now write BUOYANCY with positions:
1B 2U 3O 4Y 5A 6N 7C 8Y
Apply order 1,4,3,2,8,7,5,6:
B, Y, O, U, Y, C, A, N → BYOUYCAN
Verification / Alternative check:
The same 8-position permutation derived from EXAMPLES must be used unchanged. Applying it cleanly to BUOYANCY yields BYOUYCAN, confirming a consistent positional code rather than any alphabet shift.
Why Other Options Are Wrong:
CYOUYBAN: begins with C (position 7) instead of position 1.
CUYOYBAN: scrambles positions and drops the discovered order.
YBANCYOU: resembles a rotation/reversal, not the exact permutation.
CUOYYBAN: repeats Y incorrectly and misorders letters.
Common Pitfalls:
Assuming a reverse, assuming swapping adjacent letters only, or guessing without deriving the exact position order from the example are common errors.
Final Answer:
BYOUYCAN
