Eight girls, K, L, M, N, O, P, Q and R, are sitting in two lines, with four girls in each line. Both the lines are facing the same direction. One line is behind the other line. K is at a corner and to the immediate left of P. O is to the immediate left of M. Two persons are sitting between K and R. L is just behind P. O is between L and M. N is not in the front line. Who is sitting between P and R?

Let's denote the two rows as Front Row and Back Row, each containing 4 positions from Left (L) to Right (R): 1, 2, 3, 4. K is at a corner and to the immediate left of P: This means K must be at position 1 (left corner) so that P can be to its immediate right at position 2.Two persons are sitting between K and R: Since K is at position 1, R must be at position 4.Thus, the row containing K, P, and R has positions: Position 1 = K, Position 2 = P, Position 4 = R. The remaining position 3 in this row will be occupied by another person.L is just behind P: Since P is at position 2, L must be at position 2 of the other row. This means P is in the front row and L is in the back row.Front Row: 1: K, 2: P, 3: [Empty], 4: RO is between L and M: In the back row, L is at position 2. For O to be between L and M, O must be at position 3 and M at position 4.Let's verify: "O is to the immediate left of M". Since they face forward, position 3 (O) is to the immediate left of position 4 (M). This fits perfectly.N is not in the front line: This means N is in the back row. The remaining position in the back row is position 1, so Position 1 = N.Back Row layout: 1: N, 2: L, 3: O, 4: MRemaining position in front row: The only person left is Q, who must occupy position 3 of the front row.Front Row layout: 1: K, 2: P, 3: Q, 4: RThe question asks: "Who is sitting between P and R?"Looking at the front row layout, Q is sitting at position 3, which is directly between P (2) and R (4).
