DIRECTION: Study the following information and answer the questions given below |
(i) \['A-B'\]means 'B is father of A' |
(ii) \['A\times B'\]means 'A is sister of B' |
(iii) \['A+B'\] means 'A is brother of B' |
(iv) \['A-B'\] means 'B is mother of A' |
A) \[R+N-Q\times T\]
B) \[R-Q\times N\times T\]
C) \[R-N\times T\]
D) \[T+M-R\]
Correct Answer: A
Solution :
If R is nephew of T then the required equation must depict R as a male. Reject (b) and (c) because in these equations the symbol '?' denotes the sex of Q and N respectively. The sex of R remains unknown. Reject because these equations depict R older then T. Now, check (a) \[{{Q}_{(-)}}-T\] \[{{R}_{(+)}}-N\] Obviously, R is the nephew of T.You need to login to perform this action.
