Question

Study the given number, symbol series and answer the question that follows.

# 9 1 @ 4 * 7 ^ 5 3 # 9 1 < 5 4 @ 3 $ # 2 * 6 ! 4 2 & 9 < 3 6

Question:
How many such numbers are there which are immediately preceded by a symbol and immediately followed by an even number?

• A. 6
• B. 4
• C. 5
• D. 3

Answer 1

Answer:

D. 3

There are 3 such numbers in the series.

We need to search for the specific pattern: [Symbol] [Any Number] [Even Number]

Let's scan the series to check each symbol followed by a number:

1. # 9 1 $\rightarrow$ 9 is followed by 1 (odd)

2. @ 4 * $\rightarrow$ 4 is followed by a symbol

3. * 7 ^ $\rightarrow$ 7 is followed by a symbol

4. ^ 5 3 $\rightarrow$ 5 is followed by 3 (odd)

5. # 9 1 $\rightarrow$ 9 is followed by 1 (odd)

6. < 5 4 $\rightarrow$ < (symbol), 5 (number), 4 (even number) (1st match)

7. @ 3 $</code>$\rightarrow 3 is followed by a symbol

8. # 2 * \rightarrow$2 is followed by a symbol </p></li><li><p data-pxy="true" style="color: rgb(0,0,0); margin-top: 2px; margin-bottom: 2px;"><code color="rgb(0,0,0)" style="padding: 2px 4px; border-radius: 4px; border: 1px solid rgb(224, 224, 224); background: rgb(51, 51, 51); color: rgb(0,0,0); font-size: 0.9em; line-height: 1.4;">* 6 !</code>$\rightarrow$6 is followed by a symbol </p></li><li><p data-pxy="true" style="color: rgb(0,0,0); margin-top: 2px; margin-bottom: 2px;"><code color="rgb(0,0,0)" style="padding: 2px 4px; border-radius: 4px; border: 1px solid rgb(224, 224, 224); background: rgb(51, 51, 51); color: rgb(0,0,0); font-size: 0.9em; line-height: 1.4;">! 4 2</code>$\rightarrow ! (symbol), 4 (number), 2 (even number) (2nd match)

9. & 9 < \rightarrow 9 is followed by a symbol

10. < 3 6 \rightarrow$ < (symbol), 3 (number), 6 (even number) (3rd match)

The 3 valid numbers are 6,10,12
