UPSC ESE 2026 General Studies and Engineering Aptitude

Here is the pattern:
- Top side: E, G, K
- Right side: P, R, V
Each letter on the right is 11 letters after the corresponding top letter:
- E⟶P
- G⟶R
- K⟶V
Now look at the bottom side: O, J, F
The left side should also be 11 letters after these corresponding letters:
- O⟶Z
- J⟶U
- F⟶Q
So the left side becomes:
- Z, U, Q
That means the missing letter is Z.
