Directions: Read the following information carefully and answer the question given below.

Six persons—K, L, M, N, O, and P—are sitting around a circular table facing towards the center. Each of them uses a different brand of smartphone: Samsung, Apple, Pixel, Xiaomi, OnePlus, and Vivo, but not necessarily in the same order.

K sits opposite N, who uses Xiaomi. K, who uses Samsung, sits second to the right of the one who uses Pixel. L sits to the immediate left of K and uses Apple. O sits opposite L and uses OnePlus. P sits to the immediate right of K. The person who uses Vivo sits to the immediate left of O.

Who among the following uses the OnePlus smartphone?

The correct answer is O.

Step-by-Step Solution:

Six persons—K, L, M, N, O, and P—are sitting around a circular table facing towards the center. Let us place them in 6 positions numbered 1 to 6 in a clockwise direction, where opposite positions are pairs (1, 4), (2, 5), and (3, 6).

1. Placing K and N:
- Let K be at Position 1. K uses Samsung.
- K sits opposite N, so N is at Position 4. N uses Xiaomi.

2. Placing L, P, and the Pixel user:
- K (Position 1) sits second to the right of the person using Pixel. Since everyone faces the center, moving two steps clockwise from Position 3 leads to Position 1. Therefore, the person at Position 3 uses Pixel.
- L sits to the immediate left of K, which is Position 2. L uses Apple.
- P sits to the immediate right of K, which is Position 6.

3. Placing O and Vivo user:
- O sits opposite L (Position 2), placing O at Position 5. O uses OnePlus.
- The person to the immediate left of O (Position 5) is at Position 6 (P). Therefore, P uses Vivo.
- The only remaining position is Position 3, which must be occupied by M. Thus, M uses Pixel.

Final Seating Arrangement (Clockwise):
- Position 1: K (Samsung)
- Position 2: L (Apple)
- Position 3: M (Pixel)
- Position 4: N (Xiaomi)
- Position 5: O (OnePlus)
- Position 6: P (Vivo)

Thus, O uses the OnePlus smartphone.
