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?

A6

B4

C5

D3

Answer:

D. 3

Read Explanation:

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></code> \rightarrow 3 is followed by a symbol

(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

Conditions:

  • (i) If the first element is a number and the last, a symbol, the codes for these two are to be interchanged.

  • (ii) If the first element is an odd number and the last, an even number, the first and last elements are to be coded as $\emptyset$.

  • (iii) If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.
