(Question:276690.0)

Question:

DIRECTIONS: Answer questions  based on the following information:

A, B, C, D, E, F, G, and H are eight friends sitting around a circular table (facing the centre). They like exactly one of the following subjects viz., English, Hindi, History, Geography, Physics, Chemistry, Biology and Mathematics (in no particular order). The following points are known about their seating

arrangement: -

a. A sits opposite the person who likes History

b. The person who likes Chemistry sits to the immediate right of E.

c. G is adjacent to D and the person who likes Physics.

d. H is to the left of A and likes English.

e. B sits to the immediate left of the person who likes History and is adjacent to G who likes Hindi.

f. C is sitting exactly opposite D and is adjacent to F who likes Geography.

g. H does not sit next to someone who likes Biology or Hindi.

Which subject does A likes?

Options:
A)

English

B) Hindi
C)

Physics

D)

Mathematics

E)

Chemistry

Solution:
Ans:(d)

Number the seats 1-8 in a clockwise manner and let A be on seat 1. So, seats 1 and S will be opposite each other. Similarly, seats 2 and 6, 3 and 7 as well as 4 and 8 will be opposite each other.

Since A sits opposite the person who likes History, this person is on seat number 5.

B is to the immediate left of the person who likes History and is adjacent to G who likes Hindi.

All the people are facing the centre.

Therefore, B and G are on seat numbers 6 and 7 respectively.

Also, G = Hindi

G is adjacent to D and the person who likes Physics. Therefore, D should be on seat number 8 and should not like Physics.

Since B is the other neighbour of G, B likes Physics.

So, B = Physics. F =‘Geography

C is exactly opposite D and is adjacent to F. Therefore, C has to be on seat number 4. Thus, the person who likes History and the person who likes Geography are the neighbours of C. The person who likes History is on seat number S. Therefore, the person who likes Geography (F) has to be on seat number 3.

Now, H can be on seat number 2 (to the immediate left of A) or on seat number 5 (opposite A).

But it is given that H is to the left of A.

Therefore H is on seat number 2 and E is on seat

number 5.

So, E = History

H = English

Now, the person who likes Chemistry is to the

immediate right of E. So, C = Chemistry:

Now, A can like either Mathematics or Biology.

H sits next to A but does not sit next to someone ho likes Biology.

Therefore, A =Mathematics and D = Biology Thus, the final arrangement is:


Thus, from the arrangement above, A likes Mathematics.
