Read the following coded relationship symbols carefully:
- $A \div B$ means ' $A$ is the mother of $B$ '
- $A + B$ means ' $A$ is the father of $B$ '
- $A - B$ means ' $A$ is the sister of $B$ '
- $A \times B$ means ' $A$ is the brother of $B$ '

Based on the expression $M \div N + O - P \times Q$ , how is $Q$ related to $M$ ?

A
Grandson
B
Granddaughter
Cannot be determinedCevap
D
Son

Cevap

Cannot be determined

Decoding the expression shows that M is the mother of N, N is the father of O, and O, P, and Q are siblings. This places Q as the grandchild of M. However, no relation symbol defines the gender of Q (whether Q is male or female). Therefore, Q could be a grandson or a granddaughter, making the exact relationship impossible to determine.

Adım Adım Çözüm

Analyze the first operation

M \div N

M

is the mother of

N

(Female, 1st Generation).

The symbol

\div

specifies a mother-child relationship.

Analyze the second operation

N + O

N

is the father of

O

(Male, 2nd Generation).

The symbol

+

specifies a father-child relationship, making

M

the paternal grandmother of

O

Analyze the remaining operations

O - P \times Q

O

is the sister of

P

, and

P

is the brother of

Q

. Thus,

O

P

, and

Q

are siblings whose father is

N

The symbols

-

and

\times

define sibling relations within the same generation.

Determine the relationship and gender of

Q

Q

is a grandchild of

M

, but

Q

's gender is not stated.

P \times Q

P

is defined as the brother of

Q

, which establishes

P

's gender as male but leaves

Q

's gender unstated (could be male or female).
