Refer to the following letter, symbol series and answer the question.
(Left) Z U % & J L C @ M * N # % Q X Y & $ T E % X (Right)
If all the letters are dropped from the series, which of the following will be sixth from the left?

The correct option is %.

Step 1: Understand the given sequence

We are given the following sequence of letters and symbols with specified Left and Right positions:
(Left) Z U % & J L C @ M * N # % Q X Y & $ T E % X (Right)

Step 2: Drop all the letters from the sequence

Let's remove all alphabet letters (Z, U, J, L, C, M, N, Q, X, Y, T, E, X) from the original series.

After dropping the letters, the remaining series consisting only of symbols is:
(Left) % & @ * # % & $ % (Right)

Step 3: Count to find the 6th element from the left

Now, let's count the symbols starting from the Left side:

1st element from left: %
2nd element from left: &
3rd element from left: @
4th element from left: *
5th element from left: #
6th element from left: %

Therefore, the symbol that is sixth from the left after dropping all letters is %.
