Question

Six persons A,B,C,D,E and F are standing in a circle. B is between F and C, A is between E and D, F is to the left of D. Who is between A and F?
A. B
B. C
C. D
D. E

Answer 1

Hint:As stated in the question, 6 people are standing in a circle. It is important to notice that when two people are chosen from people standing in a circle, all other people standing in the circle will seem to stand in between these two selected people.
For example - Here, all F,B,C,D are between the selected ones i.e. A and E.
Thus when they are saying “B is between F and C” it should be assumed that B is immediately in between F and C. That is.
Realisation of this fact is really important.

Complete step by step solution :
In the given question 4 facts are important :
1. 6 people are standing in a circle
2. B is between F and C - FBC or CBF
3. A is between E and D - EAD or DAE
4. F is to the left of D - FD
Since F is to the left of D, only one pattern satisfies all the conditions.
CBFDAE in a circle. Thus D is in the immediate between F and A.
Thus option (C) is the right choice.

Note: It is important to note that though it is not mentioned that the given implications are in immediate sense, it is the only possible way to reach a single correct answer. Otherwise multiple cases satisfying the given conditions can be formed.
Thus assuming the above fact it will be easier to come to the right choice.
