'A + B' means 'A is the brother of B',
'A × B' means 'A is the father of B',
'A * B' means 'A is the mother of B',
If O + M × J + T * D, then how is T related to M?
- ADaughter
- BSister
- CDaughter-in-law
- DMother
Solution & Step-by-step Explanation
Let's break down the given coded relation expression: O+M×J+T∗D
O+M→O is the brother of M.
M×J→M is the father of J.
J+T→J is the brother of T. This means J and T are siblings, and since M is the father of J, M is also the father of T.
T∗D→T is the mother of D. This tells us that T is female.
Since M is the father of T and T is a female, T is the daughter of M.
O+M→O is the brother of M.
M×J→M is the father of J.
J+T→J is the brother of T. This means J and T are siblings, and since M is the father of J, M is also the father of T.
T∗D→T is the mother of D. This tells us that T is female.
Since M is the father of T and T is a female, T is the daughter of M.
