Option D

2

Solution :

Correct Answer: The correct option is 2.


Step-by-Step Explanation:


We are given the following series of numbers and symbols (counted from left to right):

(Left) 8 $ 3 Ω 9 % 4 6 7 1 * £ 5 # 2 + @ & (Right)


We need to find the number of symbols that satisfy the following condition:

[Number] → [Symbol] → [Symbol]

That is, a symbol that is immediately preceded by a number AND immediately followed by another symbol.


Let's analyze the sequence step-by-step from left to right to check each symbol:


1. Symbol: $

• Preceded by: 8 (Number)

• Followed by: 3 (Number)

Does not satisfy the condition.


2. Symbol: Ω

• Preceded by: 3 (Number)

• Followed by: 9 (Number)

Does not satisfy the condition.


3. Symbol: %

• Preceded by: 9 (Number)

• Followed by: 4 (Number)

Does not satisfy the condition.


4. Symbol: *

• Preceded by: 1 (Number)

• Followed by: £ (Symbol)

Matches the condition! (Sequence: 1 * £)


5. Symbol: £

• Preceded by: * (Symbol, not a number)

• Followed by: 5 (Number)

Does not satisfy the condition.


6. Symbol: #

• Preceded by: 5 (Number)

• Followed by: 2 (Number)

Does not satisfy the condition.


7. Symbol: +

• Preceded by: 2 (Number)

• Followed by: @ (Symbol)

Matches the condition! (Sequence: 2 + @)


8. Symbol: @

• Preceded by: + (Symbol, not a number)

• Followed by: & (Symbol)

Does not satisfy the condition.


9. Symbol: &

• Preceded by: @ (Symbol, not a number)

• Followed by: None (End of series)

Does not satisfy the condition.


Conclusion:

There are exactly 2 such symbols (* and +) that meet the required criteria.
