Question

Who is the wife of P ?

• A. Q
• B. R
• C. S
• D. T
• E. None of these

Answer 1

The correct option is A Q

T is a female teacher with blue dress.
T married a lawyer. Now, P is an engineer and Q is a doctor. Clearly, T married R.
R is, thus, a male lawyer with brown dress.
One couple is RT. So, the other couple is PQ
P is a male engineer and has the same dress as R i.e., brown
Q is a female doctor and has the same dress as T i.e., blue.
S is the sister of P. S is a female engineer. Now, U remains. Since there are two lawyers, so U is a lawyer.
Both S and U have either black or green dress.

	P	Q	R	S	T	U
Profession	Engineer	Doctor	Lawyer	Engineer	Teacher	Lawyer
Dress Colour	Brown	Blue	Brown	Black or Green	Blue	Black or Green
Sex	Male	Female	Male	Female	Female	Male

So, Q is the wife of P (option A)
