Q 7 D $ T 3 ! M ^ B 8 5 @ H 2 % A 9 * R 6 E S O 1 K & L # U 4 G ? P

Which letter is 10th to the left of second symbol from the right end in the series?

The correct answer is option M.

Let us analyze the given series step-by-step to find the required letter.

Step 1: Write down the given series

The sequence provided from left to right is:

Q 7 D $ T 3 ! M ^ B 8 5 @ H 2 % A 9 * R 6 E S O 1 K & L # U 4 G ? P

Step 2: Identify the symbols from the right end

Let us count the elements starting from the right end to locate the symbols:

1st element from right: P (Letter)
2nd element from right: ? (Symbol)
3rd element from right: G (Letter)
4th element from right: 4 (Number)
5th element from right: U (Letter)
6th element from right: # (Symbol)

From the right end, the 1st symbol is ? and the 2nd symbol is #.

Step 3: Move 10 places to the left from the 2nd symbol (#)

Starting from # and counting 10 positions to the left:

1st to the left of # : L
2nd to the left of # : &
3rd to the left of # : K
4th to the left of # : 1
5th to the left of # : O
6th to the left of # : S
7th to the left of # : E
8th to the left of # : 6
9th to the left of # : R
10th to the left of # : M

Therefore, the letter which is 10th to the left of the second symbol from the right end is M.
