Refer to the following number and symbol series and answer the question that follows. Counting to be done from left to right only.

(Left) @ 3 5 9 ^ % 4 $ \ @ 4 \ $ < < 6 > / 8 < & (Right)

How many such numbers are there each of which is immediately preceded by a symbol and also immediately followed by a symbol? 

Given series:

@ 3 5 9 ^ % 4 $ \ @ 4 \ $ < < 6 > / 8 < &

Condition to be checked:

Numbers which are immediately preceded by a symbol and also immediately followed by a symbol.

Symbol → Number → Symbol

Analyzing the series:

@ 3 5 9 ^ % 4 $ \ @ 4 \ $ < < 6 > / 8 < &

The numbers satisfying the condition are: 4, 4, 6, 8.

Thus there are four such numbers (4, 4, 6, and 8) that are following the above conditions.

Hence, "Option 3" is the correct answer.

Mistake Points

Immediately preceded by means immediately before or to come just before.

Immediately followed by means immediately after or to come just after.
