J, K, M, and N are sitting on a bench facing the same direction. J is sitting next to K but not next to M. N, who is sitting at the extreme right, is not sitting next to either K or M. Which of the following statements is not true?
M is sitting to the right of K
The Logic Breakdown
Let’s represent the four seats as positions 1, 2, 3, and 4 (from left to right).
N is at the extreme right: This places N in position 4.
Arrangement: _ , _ , _ , N
N is not next to K or M: Since N is in position 4, neither K nor M can be in position 3. Therefore, J must be in position 3.
Arrangement: _ , _ , J , N
J is next to K: Since J is in position 3, K must be in position 2.
Arrangement: _ , K , J , N
M is the remaining person: M must occupy position 1.
Arrangement: M , K , J , N
Final Seating Order
| Position 1 (Left) | Position 2 | Position 3 | Position 4 (Right) |
|---|---|---|---|
| M | K | J | N |
Evaluating the Statements
Option 1: "M is sitting to the right of K" — False. (M is to the left of K).
Option 2: "K is sitting next to M" — True.
Option 3: "M is at one end" — True. (M is at the left end).
Option 4: "J is between K and N" — True.
The statement that is NOT true is Option 1.
