Six letters Q, Z, V, T, L and A are written on different faces of a dice. Two positions of this dice are shown in the figures below. Find the letter on the face opposite to Q.

To find the letter on the face opposite to Q, we analyze the two given positions of the dice shown in the image:

Position 1: The visible faces are Q (top), Z (left-front), and V (right-front).
Position 2: The visible faces are T (top), L (left-front), and V (right-front).

Since the letter V is present on the right-front face in both positions, we can determine the arrangement of the faces surrounding it:
1. From the first position, V is adjacent to Q and Z.
2. From the second position, V is adjacent to T and L.
3. Since V is adjacent to Q, Z, T, and L, the only remaining face of the six-sided dice (which has letters Q, Z, V, T, L, and A) is A. Therefore, the face opposite to V is A.

Now, let's look at the remaining four faces (Q, Z, T, L) that form a ring around V:
- In the first position, looking at the face V, the face Q is at the top and Z is to its left (moving counter-clockwise from top to left: Q to Z).
- In the second position, looking at the face V, the face T is at the top and L is to its left (moving counter-clockwise from top to left: T to L).
- To maintain this cyclic order (Q → Z → T → L), the face opposite to Q must be T, and the face opposite to Z must be L.

Thus, the letter on the face opposite to Q is T.
