Question
Question:A, B, C, D, E, F and G are sitting in a row facing North:
- F is to the immediate right of E.
- E is 4th to the right of G.
- C is the neighbour of B and D.
- Person who is third to the left of D is at one of ends. Who are to the left of C?
Solution 1
To solve this problem, we need to follow the given clues step by step:
- F is to the immediate right of E. This means E is to the immediate left of F.
- E is 4th to the right of G. This means G is 4th to the left of E. So, the arrangement so far is G _ _ _ E F.
- C is the neighbour of B and D. This means C is between B and D. But we don't know where to place them yet.
- Person who is third to the left of D is at one of ends. This means D must be fourth from the right end. So, the arrangement so far is G _ _ _ E F _ D.
- Now, we know that C is between B and D. So, the arrangement becomes G _ _ _ E F B C D.
- The only remaining person is A. So, the final arrangement is G A _ _ E F B C D.
So, the people to the left of C are B, F, E, _, A, and G.
Solution 2
To solve this problem, we need to follow the given clues step by step:
-
"F is to the immediate right of E." This means E is to the immediate left of F.
-
"E is 4th to the right of G." This means G is 4th to the left of E. So, the arrangement so far is G _ _ _ E F.
-
"C is the neighbour of B and D." This means C is between B and D. But we don't know where to place them yet.
-
"Person who is third to the left of D is at one of ends." This means D must be fourth from the right end. So, the arrangement so far is G _ _ _ E F _ D.
Now, we know that C is between B and D, so we can place B and C. The arrangement becomes G _ _ _ E F B C D.
The only two people left are A and H. Since there are only two spots left, we can fill them in. The final arrangement is G A _ E F B C D.
The people to the left of C are G, A, _, E, F, and B.
