D, E, F, G, K, L এবং M একটি গোলাকার টেবিলের চারপাশে কেন্দ্রের দিকে মুখ করে বসে আছেন।
D, K-এর ডানদিকে চতুর্থ স্থানে বসে। L-এর বাম দিক থেকে গণনা করলে L এবং G-এর মধ্যে মাত্র দুজন ব্যক্তি বসে। F, E-এর বাম দিকে তৃতীয় স্থানে বসে। M হল E এবং G-এর নিকটতম প্রতিবেশী।
M-এর বাম দিক থেকে গণনা করলে D এবং M-এর মধ্যে কতজন ব্যক্তি বসে আছেন?
দুজন
চারজন
তিনজন
একজন
চারজন
Fix the reference point (e.g., K) and place others relative to it. Since M is adjacent to E and G, placing M first often locks the remaining seats.
Fix the reference point (e.g., K) and place others relative to it. Since M is adjacent to E and G, placing M first often locks the remaining seats.
Establish the Base
Place K at the bottom. Since D is 4th to the right of K, D is opposite K. (Positions: 1=K, 2, 3, 4=D, 5, 6, 7)
Place M, E, G, F
M is neighbor to E and G. F is 3rd to left of E. Testing the sequence: If E is at 6, M is at 5, G is at 4. F is 3rd left of E (6 → 5 → 4 → 3), so F is at 3. L must be at 2. Counting left from M: 1(G), 2(L), 3(D), 4(K), 5(F), 6(E) = 6 slots filled, correct.
Final Counting
The order clockwise is K(1), D(2), L(3), G(4), M(5), E(6), F(7). Counting left from M (clockwise direction): M → E(1), F(2), K(3), D(4). There are 4 people between D and M.
A: Two is incorrect because the gap between D and M involves E, F, K. C: Three is incorrect because the count must include the specific sequence of seated persons. D: One is incorrect as it underestimates the gap.
B is correct because mapping the circular arrangement positions K(1), D(2), L(3), G(4), M(5), E(6), F(7) results in 4 people (E, F, K, D) between M and D when counting from the left of M.
In circular puzzles, always verify the 'left' and 'right' orientation relative to the centre. If facing the centre, clockwise is left and anti-clockwise is right.
