Directions (96-100): Study the given series of numbers, symbols and alphabets and answer the questions based on it.

2 F T % 4 Y 8 $ B 9 P M 6 # 7 V A Ω 5 I E ∞ J 9 I β 6 N 4 ϕ L K 3 µ

How many symbols are there in the given series each of which is immediately followed and immediately preceded by a number?

To find the symbols that satisfy the given condition, we need to analyze the series step-by-step and search for a specific pattern:
Number - Symbol - Number

Let's write down the given series:
2 F T % 4 Y 8 $ B 9 P M 6 # 7 V A Ω 5 I E ∞ J 9 I β 6 N 4 ϕ L K 3 µ

First, let's identify all the symbols in the series and check their preceding and following characters:
1. % is preceded by T (alphabet) and followed by 4 (number). (Does not satisfy)
2. $ is preceded by 8 (number) and followed by B (alphabet). (Does not satisfy)
3. # is preceded by 6 (number) and followed by 7 (number). (Satisfies)
4. Ω is preceded by A (alphabet) and followed by 5 (number). (Does not satisfy)
5. ∞ is preceded by E (alphabet) and followed by J (alphabet). (Does not satisfy)
6. β is preceded by I (alphabet) and followed by 6 (number). (Does not satisfy)
7. ϕ is preceded by 4 (number) and followed by L (alphabet). (Does not satisfy)
8. µ is preceded by 3 (number) and is the last element. (Does not satisfy)

Thus, there is only one such symbol, which is # (in the sequence 6 # 7), that is immediately preceded by a number (6) and immediately followed by a number (7).

Therefore, the correct answer is One.
