If T + U means T is the mother of U; T – U means T is husband of U, T ÷ U means T is son of U and T × U means T is sister of U. Then M ÷ N + O - P shows what relation of N with P?
mother-in-law
Understanding Blood Relations in Reasoning
This question asks us to determine the relationship between two individuals, N and P, based on a coded expression involving several people and symbols. We need to decode the meaning of each symbol and then trace the relationships step by step through the expression M ÷ N + O - P.
Decoding the Symbols
Let's first understand what each symbol represents according to the given information:
- T + U means T is the mother of U. (Addition represents Mother)
- T – U means T is husband of U. (Subtraction represents Husband)
- T ÷ U means T is son of U. (Division represents Son)
- T × U means T is sister of U. (Multiplication represents Sister)
We are interested in the relationship shown by the expression: M ÷ N + O - P.
Analyzing the Expression Step-by-Step
We will break down the expression M ÷ N + O - P from left to right to establish the connections between M, N, O, and P.
-
M ÷ N:
According to the rule T ÷ U means T is son of U, M ÷ N means M is the son of N.
This tells us that N is a parent of M. N could be M's father or mother.
-
N + O:
According to the rule T + U means T is the mother of U, N + O means N is the mother of O.
From this, we know that N is female (she is a mother). Since N is the mother of O and also a parent of M (from the first step), N is the mother of both M and O. This means M and O are siblings.
-
O - P:
According to the rule T – U means T is husband of U, O - P means O is the husband of P.
This tells us that O is male and P is female. P is the wife of O.
Determining the Relation of N with P
Now let's combine the information we have gathered:
- N is the mother of O (from step 2).
- O is the husband of P (from step 3).
So, N is the mother of O, and O is married to P. P is O's wife.
The relation of N with P is the relation of O's mother with O's wife.
The mother of one's husband is called the mother-in-law.
Therefore, N is the mother-in-law of P.
The question asks for the relation of N with P.
N is the mother-in-law of P.
Concluding the Relationship Analysis
By decoding the symbols and following the chain of relationships, we found that N is the mother of O, and O is the husband of P. This establishes N as the mother-in-law of P.
Revision Table: Blood Relation Codes
| Symbol | Meaning | Example (T, U) | Relationship |
|---|---|---|---|
| + | Mother of | T + U | T is mother of U |
| – | Husband of | T – U | T is husband of U |
| ÷ | Son of | T ÷ U | T is son of U |
| × | Sister of | T × U | T is sister of U |
Additional Information: Understanding In-Law Relations
In-law relationships are created through marriage. Some common in-law relations include:
- Mother-in-law: The mother of one's spouse.
- Father-in-law: The father of one's spouse.
- Son-in-law: The husband of one's child.
- Daughter-in-law: The wife of one's child.
- Brother-in-law: The brother of one's spouse, or the husband of one's sibling.
- Sister-in-law: The sister of one's spouse, or the wife of one's sibling.
These questions test your ability to follow instructions and deduce relationships logically based on given rules. Practice with different symbol combinations and family structures can help improve your proficiency in blood relation reasoning problems.
