Refer to the given number, symbol series and answer the question that follows. Counting to be done from left to right only. All numbers are single-digit numbers.
(Left) 8 $ 3 Ω 9 % 4 6 7 1 * £ 5 # 2 + @ & (Right)
How many such symbols are there, each of which is immediately preceded by a number and also immediately followed by another symbol?
Correct Answer :
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.
