Refer to the following number and symbol series and answer the question given below. Counting should be from left to right only.

If all the symbols are removed from the series, which of the following will be sixth from the right?

2. B

Appeared in: DSSSB 6 September 2024

Explanation

• The initial series provided is: @ 3 & 9 1 & 0 & 3 2 1 5 & 4 # 6 & 7.
• The first step is to remove all non-numeric symbols (@, &, #) from the series.
• The resulting series of numbers is: 3 9 1 0 3 2 1 5 4 6 7.
• The final step is to count six positions from the right end of this new series.
• Counting from the right: 7 (1st), 6 (2nd), 4 (3rd), 5 (4th), 1 (5th), and 2 (6th).
• Therefore, the sixth element from the right is 2.

Why Other Options Were Wrong

• Option A: The number 8 does not appear anywhere in the original series.
• Option B: After removing the symbols, the number 5 is the fourth element from the right, not the sixth.
• Option C: After removing the symbols, the number 7 is the first element from the right.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Number and Symbol Series as background academic context rather than a clinical decision trigger.
• This type of logical reasoning question assesses attention to detail and the ability to follow multi-step instructions accurately.
• While not a clinical question, these cognitive skills are fundamental in nursing for tasks like medication administration, reading patient charts, and interpreting lab results, where precision is critical for patient safety.
• What if? If the question asked for the sixth element from the left after removing symbols, the answer would also be 2. The series is 3, 9, 1, 0, 3, 2... and the 6th number is 2.

How to Approach the Question

• First, carefully read the entire question to understand the given series and the specific instructions (e.g., remove symbols, count from the right).
• It's helpful to write down the original series on a piece of paper to manipulate it without losing track.
• Identify and remove all the characters that fit the specified category (in this case, all symbols: @, &, #).
• Write down the new, filtered series, which contains only the numbers.
• From the specified direction (the right end), carefully count the required number of positions (six).
• Double-check your counting and match the resulting number with the given options.
