(Left) B R © # # # W & S @ Z @ @ A & L @ @ I © O © (Right)
How many such letters are there each of which is immediately preceded by a letter and also immediately followed by a symbol?
Analyzing the Letter Symbol Series
The task is to find the number of letters in the given series that satisfy two conditions simultaneously: being immediately preceded by another letter and immediately followed by a symbol. We will examine the series B R © # # # W & S @ Z @ @ A & L @ @ I © O © from left to right.
Identifying Qualifying Letters
Let's break down the series and check each letter:
- B: Preceded by nothing (start), followed by R (letter). Does not meet the criteria.
- R: Preceded by B (letter), followed by © (symbol). Meets both criteria.
- W: Preceded by # (symbol). Does not meet the criteria.
- S: Preceded by & (symbol). Does not meet the criteria.
- Z: Preceded by @ (symbol). Does not meet the criteria.
- A: Preceded by @ (symbol). Does not meet the criteria.
- L: Preceded by & (symbol). Does not meet the criteria.
- I: Preceded by @ (symbol). Does not meet the criteria.
- O: Preceded by © (symbol). Does not meet the criteria.
Symbols like ©, #, &, @ are ignored as they are not letters.
Counting the Letters
Only one letter, 'R', fits the conditions of being immediately preceded by a letter and immediately followed by a symbol.
Therefore, the total count is 1.
Important Questions from Arrangement and Pattern
