EX.
Study the following information carefully to answer the given question
1. A, B, C, D, E ,F and G are sitting around a circle and are facing the centre.
2. G is second to the left of C, who is to the immediate left of F.
3. A is third to the left of E.
4. B is between D and E.
i)which of the following is false ?
a. A is the fourth to the right of E. b. G is to the immediate right of D . c. F is the third to the right of D . d. B is the immediate left of D . e. None of these
ii) Which of the following is true?
a. C is fourth to left of B . b. A is to the immediate right of G. c. D is second to the left of E. d. B is second to the right of G.
e. None of these
iii) Which of the following pair has the first person sitting to the immediate left of the second person?
a. BE b. CA c . GD d. DG e. None of these
iv) Which of the following is the positions of F?
a. Fourth to the right of D. b. To the immediate left of C. c. Between A and C. d. To the immediate right of A e. None of these.
Solutions.
We first of all marki the seven balank polsitions around a circle . Now , G is second to the left of C and C is to the immediate left of F . We mark their positons as shown . also , B is between D and E. tHUS , D , B, E sit together and occupy the three consecutive blank positions . Now , only one position remains blank betwen G and C, and this must be occupied by A. now , D, B, E may sit in any of the postions ( D,B,E) or ( E,B,D). But A is third to the left of E only when they sit in the order ( D, B, E). Thus we mark their postions as shown.
1. Clearly , F is fourth to the right of D . So , (c) is false . hence , the answer is (c)
2. C is third to the left of B. So, (a) is false
A is to the immediate right of G. So , (b) is true.
D is second to the right of E. So, (c) is false .
B is second to the left of G. So, ( d) is false .
Hence , the answer is (b)
3. Clearly , only in the pair DG , the first person D sits to the immediate left to the second person G . Hence the answer is (d).
4. C sits between A and F ; F sits between E and C ;E sits between B and F: D sits between G and B. So, none of the given groups satisfies the given condition.
5. Clearly, F's postion is . fourth to the right of D.
. to the immediate right of C.
. between C and E
.Second to the right of A.
Hence, the answer is (a).
