IBPS SO Prelims Exam Model Paper 5

Let us first decode the given symbols and then draw a family tree.Now draw family tree using following notations:
Using statement number 1:
P % Q # R + S % T means P is the son of Q, Q is the mother of R, R is the brother of S, S is the son of T.Clearly we can say Q is the wife of T .
Hence, the statement 1 is incorrect.
Using statement number 2:
P % Q # R $ S % T means P is the son of Q, Q is the mother of R, R is the sister of S, S is the son of T.Clearly we can say Q is the wife of T.
Hence, the statement 2 is incorrect.
Using statement number 3:
P % Q # R $ S & T means P is the son of Q, Q is the mother of R, R is the sister of S, S is the father of T.Clearly in this option Q is the grandmother of T
Hence, the answer is P % Q # R $ S & T
Using statement number 4:
Q & P + R % S $ T means Q is the father of P, P is the brother of R, R is the son of S, S is the sister of T.Clearly we can say that Q is the brother in law of T.
Hence, the statement 4 is incorrect.
