Question
In a certain code language, ‘A + B’ means
‘A is the mother of B’; ‘A – B’ means ‘A is the wife of B’; ‘A × B’ means ‘A is the father of B’ and ‘A ÷ B’ means ‘A is the sister of B’. Based on the above, how is P related to T if ‘P + Q − R × S ÷ T’?Solution
-
P is mother of Q → P → Q
-
Q is wife of R → R → Q (husband)
-
R is father of S → R → S
-
S is sister of T → S → T
Now trace P → T : P → Q → R → S → T Relationships: P is mother of Q Q is wife of R → Q and R are married R is father of S → R + Q = parents of S S is sister of T → S and T have the same parents So S and T are siblings (children of R and Q) P is mother of Q, so P is mother-in-law of R , grandmother of S Therefore, P is grandmother of S , and since S and T are siblings, P is also grandmother of T
