A ÷ B means 'A is the daughter of B'.
Which of the following expressions means 'U is the daughter of Q'?
A. K - U ÷ Z X Q
B. Q - Z x U ÷ K
C. Q - Z ÷ U × K
D. K - Z ÷ U x Q
Answer: Option B
Solution (By JKSSB Mock Tests)
In option B (Q - Z x U ÷ K), Q is the mother of Z, Z is the sister of U. This means Q is the mother of U. Since U ÷ K means U is a daughter (female), U is the daughter of Q.
Explanation:
E is the daughter of B, and D is the brother of E, so D is the son of B. A is the mother of B. Therefore, A is the grandmother (maternal or paternal depending on B's gender) of D.
If A + B means A is the brother of B; A - B means A is the sister of B; and A x B means A is the father of B. Which of the following means that C is the son of M?
Explanation:
In option D, M x N means M is the father of N. N - C means N is the sister of C, so M is also the father of C. C + F means C is the brother of F, which establishes that C is male. Therefore, C is the son of M.
