Which letter will be 13th to the left of 11th letter from the right in the following series of letters?
W Q E T R Y I P U O A G S D F H L K J B C X M V Z N

  • A.Y
  • B.F
  • C.E
  • D.V

Answer: C

Correct answer: E

The series has twenty-six letters, so the eleventh from the right is at position

\[ 26 - 11 + 1 = 16 \]

Counting into W Q E T R Y I P U O A G S D F H..., position 16 is H.

Thirteen to the left of H is position 3:

\[ 16 - 13 = 3 \rightarrow E \]

Working in positions rather than counting letters twice keeps the two steps independent.
