Read the following information to answer the question that follows.
P – Q means Q is father of P P × Q means Q is brother of P P ÷ Q means Q is wife of P P + Q means Q is sister of P Which of the following means M is the grandfather of T?
Explanation:
Option 1:
M is the brother of N, who is the sister of L So, M is also the brother of L. L is the wife of C who is the father of T. Thus, M cannot be the grandfather of T.
Option 2:
M and T are at the same position in option 2 as in 1. Also, since the symbols and their position in option 2 is the same as that in option 1, the relation between the two is also the same.
Option 3:
M is the father of F who is the sister of L. L is the brother of Z. Thus, M is the father of F, L and Z. Z is the wife of T. Thus M cannot be the grandfather of T.
Thus, none of the given options means M is the grandfather of T.
Hence, option (d).
Alternatively,
Except for the ‘−’ sign, all the other signs convey a relationship in the same generation. For M to be the grandfather of T, there should be two ‘−’ signs. This is not present in any of the options.
