Let's have a look at different types of questions of Blood Relations.
Mr Rajat Chopra and his wife Nikita Chopra have 3 sons whose names are Ramesh, Suresh and Umesh. Mishra family is a neighbour of the Chopra’s.
Mr Amit Mishra and his wife Neha Mishra have 2 daughters whose names are Payal and Ruchi. The two neighbouring families go to Kerala for a vacation. They decide to go for boating but no boat could carry more than 3 members. So they hire 3 boats. None of the children knows how to row a boat, so at least one of the adults have to be there on each boat. Moreover, no boat has all three members of the same family.
Q.1. If the three children from the Chopra family ride in different boats, then which of the following is definitely false?
(I) Rajat and Nikita are rowing in the same boat.
(II) Amit and Neha are rowing in the same boat.
A: I Only
B: II Only
C: Both I and II
D: Neither I nor II
Statement II can be true as well as false. It can be true if the two people travel in one boat while Amit and Nikita row the other two boats. Hence nothing can be said with certainty about statement II. Thus the correct answer is option A
Q.2. If Nikita and Amit are on the same boat, then which of the following cannot be the combination of people on any boat?
Q.3. If Neha and Ruchi are on the same boat, which of the following could be a list of people on another boat?
Q.4. If Rajat and Amit are in the same boat and each of the three brothers are on different boats, then which of the following is necessarily true?
There are 6 members (A, B, C, D, E, F) in a family who are spread across 3 generations. There are two couples in the family and no one from the third generation is married. E is the wife of C. F and B are the only people belonging to their generation and they are also a couple. There are 4 male members in the family.
Q.5. Which of the following must be true?
Sol: Given: P’s daughter is S’s sister → R and S are children of P
→ Q is the maternal aunt of R and S
Q.7. Pointing to a photograph on the wall, Anil says to Nitesh, “ The person in the photograph is the son of my mother’s sister and is your brother”. Which of the following is true?
In this type of question, the statements are given in the form of puzzles.
Q.8. In a family of W, X, Y, and Z, W and X are brothers; while Y and Z are sisters. How are X and Y related if W’s son is Z’s brother?
Sol: From the statement, a simple diagram can be sketched to analyse the relation between Y and Z.As the total generations in the question are two, the number of rows in the diagram will also be two. The sign (+) implies male, while (-) implies female.
Q.9. Consider the following statements and answer the given question.
If L + M => L is the husband of M,
L / M => L is the sister of M and
L * M => L is the son of Y, then
How is W and Z related from the following statement: W * X + Y / Z?
Sol: This can be solved by dividing the question and solving from left to right. Now a simple diagram can be made by mentioning the gender and their relations as given below:
Thus, it is easily seen that W is the nephew of Z.
Q.10. That girl is Ramu’s sister’s uncle’s wife’s daughter. How is that girl related to Ramu?
Ans: This question seems confusing initially; but, breaking the sentence into parts and then analyzing the relation can be extremely easy. Now this sentence can be broken as,
Ramu’s sister’s uncle = Ramu’s uncle
Ramu’s uncle’s wife’s son = Ramu’s cousin
Therefore, that girl is the cousin of Ramu.
