Introduction / Context:
This question uses the popular style of number and letter puzzles where short codes represent well known facts. Typical examples are 7 D in a W for 7 days in a week and 26 L in the A for 26 letters in the alphabet. Here, the code is 64 S on CB. The puzzle tests whether you can decode the initials into a meaningful English statement based on common knowledge, in this case something related to the number 64 and the letters S and CB.
Given Data / Assumptions:
- The coded phrase is 64 S on CB.
- We know S often stands for squares, seconds, or students in similar puzzles.
- CB could reasonably stand for chessboard, circuit board, or college bench, among others.
- The options provide four possible expansions, only one of which matches a widely recognized fact.
- Most people know that a standard chessboard has 64 squares arranged in an 8 by 8 grid.
Concept / Approach:
The concept is to identify a familiar fact that uses the number 64 and something abbreviated as S on CB. One of the most famous such facts is that a standard chessboard contains 64 squares. Here, S stands for squares and CB stands for chessboard. The full sentence is 64 squares on a chessboard. The other options in the question attempt to assign different words to these initials but do not correspond to standard, universally known facts, which is a key requirement for this class of puzzle.
Step-by-Step Solution:
Step 1: Interpret 64 as sixty four.
Step 2: Consider natural words starting with S that could follow a number, such as squares, seconds, students, or seats.
Step 3: Consider likely meanings for CB, such as chessboard, circuit board, or class bench.
Step 4: Recall that a standard chessboard is an 8 by 8 grid, giving 8 multiplied by 8 equals 64 squares total.
Step 5: Form the sentence sixty four squares on a chessboard and see that it matches both the initials and a well known fact.
Step 6: Compare this with the answer choices and confirm that 64 squares on a chessboard is given explicitly as one option.
Verification / Alternative check:
To check the correctness, visualize a chessboard. It has eight rows and eight columns of alternating colored squares. Multiplying 8 by 8 gives 64, confirming the total number of squares. None of the other proposed expansions, such as 64 sports on college broadcasts or 64 students on a class bench, are well known fixed facts with the number 64. The strong link between chessboard and the number 64 confirms that 64 squares on a chessboard is the intended decoding.
Why Other Options Are Wrong:
64 sports on college broadcasts: There is no common rule that exactly 64 sports are broadcast by a college, so this is arbitrary.
64 steps on city bridges: Different bridges have different numbers of steps; there is no famous rule about 64 steps.
64 students on a class bench: Class sizes vary widely, and this would be overcrowded in most real settings.
Common Pitfalls:
Some learners try to force the letters to fit unusual phrases rather than looking for a standard trivia fact. Another pitfall is to forget the strong association between the number 64 and chess. Remember that number and letter puzzles aim at simple, widely known facts, not complicated or region specific details. Keeping that in mind makes 64 squares on a chessboard the obvious and correct solution.
Final Answer:
The abbreviation 64 S on CB stands for
64 squares on a chessboard.
