Question

Which of the following is a group of female members?

• A. QSR
• B. QST
• C. QSU
• D. QTU
• E. UST

Answer 1

The correct option is B QST

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

The females in the group are Q, S and T. (option B)
