Refer to the given number and symbol series and answer the question that follows. Counting to be done from left to right only.(Left) 2 & % 4 6 @ 3 Ω 9 # 1 * 8 £ 6 1 7 # (Right)

How many such symbols are there, each of which is immediately preceeded by an even number and also immediately followed by an even number?

​To solve this problem, we need to examine the sequence and identify symbols that satisfy the following conditions:

The symbol is preceded by an even number.

The symbol is followed by an even number.

2 & % 4 6 @ 3 Ω 9 # 1 * 8 £ 6 1 7 #

Scan each element from left to right:

Check if a symbol is immediately preceded and followed by even numbers.

Identify the even numbers in the sequence:

Even numbers are: 2,4,6,8,6.

Examine each symbol and its neighbors:  

So, there is only one such pair.

Thus, correct option is (b).
