Refer to the following letter and symbol series and answer the question that follows. Counting to be done from left to right only.
(Left) N T © Z © * U £ H W S * V C * O © W # € E K (Right)
How many such symbols are there each of which is immediately preceded by a letter and also immediately followed by a symbol?
Series Analysis
The task is to analyze the given sequence of letters and symbols to find out how many symbols meet specific criteria. The sequence is read strictly from left to right.
The given series is:
$N T © Z © * U £ H W S * V C * O © W # € E K$
Identifying Letters and Symbols
First, let's identify the letters and symbols in the series:
- Letters: N, T, Z, U, H, W, S, V, C, O, W, E, K
- Symbols: ©, *, £, *, *, *, ©, #, €
Conditions for Symbols
We need to find symbols that satisfy both of the following conditions simultaneously:
- The character immediately preceding the symbol must be a letter.
- The character immediately following the symbol must be another symbol.
Step-by-Step Symbol Check
Let's examine each symbol in the series from left to right and check if it meets the required conditions.
| Position | Symbol | Preceding Character | Is Preceding a Letter? | Following Character | Is Following a Symbol? | Meets Conditions? |
|---|---|---|---|---|---|---|
| 3 | © | T | Yes | Z | No (Letter) | No |
| 5 | © | Z | Yes | * | Yes | Yes |
| 7 | * | © | No (Symbol) | U | No (Letter) | No |
| 9 | £ | U | Yes | H | No (Letter) | No |
| 14 | * | S | Yes | V | No (Letter) | No |
| 17 | * | C | Yes | O | No (Letter) | No |
| 19 | © | O | Yes | W | No (Letter) | No |
| 22 | # | W | Yes | € | Yes | Yes |
| 24 | € | # | No (Symbol) | E | No (Letter) | No |
Counting Qualifying Symbols
By analyzing each symbol based on the given conditions, we found two symbols that meet the criteria:
- The second '©' symbol (at position 5), which is preceded by the letter 'Z' and followed by the symbol '*'.
- The '#' symbol (at position 22), which is preceded by the letter 'W' and followed by the symbol '€'.
Therefore, there are exactly 2 such symbols in the series.
Important Questions from Arrangement And Pattern (Notes)
- If the digits in the number '758462139' are arranged in ascending order, then how many digits remain in the same place?
Each of the digits in the number 8642571 is arranged in ascending order from left to right. What will be the sum of the digits which are fourth from the left and second from the right in the new number thus formed?
- Arrange the following is the correct sequence with regard to 'the five-stage model' of conditions required for learning.
(1) Transformation
(2) Presentation
(3) Engagement
(4) Reflection
(5) Exploration. - Arrange the steps of research in a sequential order
(1) Identifying a research problem
(2) Specifying the purpose for research
(3) Reviewing the literature
(4) Collecting the data
(5) Reporting and evaluating research
(6) Analysing and interpreting the data
Choose the correct sequence. Refer to the following letter, number, symbol series and answer the question that follows.
(Left) C H * * 8 5 9 * 4 9 1 6 5 L # 5 6 5 £ * K B (Right)
If all the numbers are dropped from the series, which of the following will be fifth from the left?
