Passage:
(i) There are two lecturers, two singers, one doctor and one engineer in a group of six people- A, B, C, D, E & F.
(ii) The doctor C is married to A who is a lecturer.
(iii) The engineer is married to B who is of the same profession as that of E.
(iv) C, A, B & F are married couples and nobody in the group has the same profession.
(v) E is F’s brother.
C (doctor) is married to A (lecturer), F (Engineer) is married to B (Singer).
By reversing the word we can write SYSTEM as METSYS.
A(mother) and C(father) is married couple and has two children B(male) and D. So, we can say B is the brother but there is no information given regarding the gender of D. Therefore, we can’t say brother is B only.
