## Blood Relation Questions and Answers Part-2

Data for Questions 1 & 5 : If a + b means a is daughter of b,

1. What does the relation p ¥ q – r show?
a) p is son-in-law of r
b) p is brother of r
c) r is wife of p
d) None of these

Explanation: p ¥ q – r can be read as p is the brother of q and q is the husband of r. Thus p must be the brother-in-law of r. Hence, option (d) is correct

2. If h + i ¥ j + k × l + m ¥ n, then what is the present generation of h. Assume that the oldest generation in this group is the first generation?
a) $2^{nd}$
b) $3^{rd}$
c) $4^{th}$
d) None of these

Explanation: h + i × j + k × l + m ¥ n means h is the daughter of i, i is the brother of j, j is the daughter of k, k is the brother of l, l is the daughter of m and m is the brother of n. Thus, if m and n are the first generation, k and l are the second, i and j are the third generation, h is the fourth generation. To solve this question in short, you only need to realise that the use of the + sign signifies a generation change. Since the + sign is used thrice, h must be the fourth generation. Hence, option (c) is the answer.

a) a + b × c
b) a – b ¥ c
c) a + b + c
d) a + b - c

Explanation: Option (b) says: a – b ¥ c, this does not hold since a must be the husband of b (who is a female) and b is the brother of c (which cannot happen). Hence, option (b) is the answer.

a) b is the brother of a

Explanation: a × b ¥ c ¥ d means a is the brother of b, b is the brother of c and c is the brother of d. This makes options (a), (b) and (d) as correct. Only option (c) is not necessarily true since d could be b’s sister too. Hence, (c) is the answer.

a) Niece
b) Sister
c) Mother
