Six friends are watching a movie sitting in a row. E is sitting next to Q. P is sitting next to G. Q is sitting with R, who is at the left end. G is sitting second to the right of Q. E is to the left of P and F. Q and E are sitting together. What is the position of F?

Let's determine the placement of the 6 slots from Left (1) to Right (6):"R is at the left end" $\to$ Slot 1 = R."Q is sitting with R" $\to$ Slot 2 = Q."G is sitting second to the right of Q" $\to$ Slot 4 = G (since Q is at 2, $2+2=4$)."Q and E are sitting together" / "E is sitting next to Q" $\to$ Slot 3 = E (since Slot 1 is taken by R)."P is sitting next to G" $\to$ P could be at Slot 5 or 6. Let's check: "E is to the left of P and F." This is satisfied in both configurations.Let's place the remaining people: We have Slots 5 and 6 left for P and F. Since P is next to G (Slot 4), P must be at Slot 5.This leaves Slot 6 for F.The complete arrangement from left to right is:R - Q - E - G - P - FTherefore, F is at the right end of the row.
