A party consists of a grandmother, a father, a mother, four sons, their wives, and one son and two daughters to each of the sons. How many females are there in all?
A. 16
B. 12
C. 18
D. 14
Answer: Option D
Solution (By JKExamLibrary)
Let's count the females: 1 grandmother + 1 mother + 4 wives of the sons + 8 daughters (2 daughters for each of the 4 sons). Total females = 1 + 1 + 4 + 8 = 14.
A + B means 'A is the mother of B';
A - B means 'A is the husband of B';
A x B means 'A is the son of B';
A + B means 'A is the daughter of B';
If W × Z + Y ÷ X, then how is X related to Z
Explanation:
Z is the mother of Y, and Y is the daughter of X. Thus, X and Z are parents of Y. Based on the relation symbols, X is derived as the corresponding female/daughter relative in the alternate chain.
If P $ Q means P is the brother of Q; P # Q means P is the mother of Q; P * Q means P is the daughter of Q. If the expression is A # B $ C * D, who is the father?
Explanation:
A # B means A is the mother of B. B $ C means B is the brother of C, so A is also the mother of C. C * D means C is the daughter of D. Since A is already the mother of C, D must be the father of C (and B).
'A # B' means 'A is brother of B' 'A @ B' means 'A is daughter of B' 'A & B' means 'A is wife of B' If L & M # N @ A & B # C, then how is L related to C?
Explanation:
L & M → L wife of M. M # N → M brother of N. N @ A → N daughter of A. A & B → A wife of B. So A and B are parents of N. M being brother of N is their son. Thus L is daughter-in-law of A and B. B # C → B brother of C, so C is sibling of B. In Indian family context, brother's son's wife is also called daughter-in-law; hence L is daughter-in-law of C as well.
