‘A ÷ B’ means ‘A is the father of B’. 'A * B' means 'A is brother of B'. 'A + B' means 'A is the mother of B'. ‘A – B’ means ‘A is sister of B’. If P + Q + R – S ÷ T * U, then how is T related to Q?
A. Brother
B. Nephew
C. Son
D. grandson
Answer: Option D
Solution (By JKExamLibrary)
P + Q → P mother of Q. Q + R → Q mother of R. R – S → R sister of S, so S brother. S ÷ T → S father of T. So Q is mother of S, S is father of T, hence T is grandson of Q.
Explanation:
S and T are siblings, and P is their parent. Q's mother is the sister of P, and both are children of M. Therefore, M is the grandparent of P's children (S and T). Since the gender of M is not defined, M can be either Grandfather or Grandmother.
