Given: A = 1 min, B = 2 min, C = 8 min, D = 11 min. Only 2 can cross at a time with 1 lamp. Pair walks at slower person’s speed.
Best (exam) strategy:
1) A + B cross → 2 min
2) A returns → 1 min
3) C + D cross → 11 min
4) B returns → 2 min
5) A + B cross → 2 min
Total time = 2 + 1 + 11 + 2 + 2 = 18 minutes
Answer: 18 minutes
Given: X is married to A. A is a lawyer. C is not a doctor. Y is not married to an engineer. Z is not married to a doctor.
Step 1 (Professions):
A is a lawyer.
So the remaining two professions are doctor and engineer for B and C.
Given C is not a doctor ⇒ C must be an engineer.
Therefore, B must be a doctor.
Step 2 (Marriages):
X is married to A (fixed).
Remaining men for Y and Z are B and C.
Z is not married to a doctor, and B is the doctor ⇒ Z cannot marry B ⇒ Z is married to C.
So Y is married to B.
Final Matches:
X – A (Lawyer)
Y – B (Doctor)
Z – C (Engineer)
Given:
D is the grandmother of A and mother of B ⇒ B is A’s parent.
C is the wife of B ⇒ C is spouse of A’s parent.
Therefore, C is A’s mother.
Answer: Mother
From the statements:
• C is wife of B ⇒ B is male, C is female.
• D is grandmother/mother ⇒ D is female.
• F is granddaughter ⇒ F is female.
So far, confirmed genders:
Male: B
Female: C, D, F
The problem says there are two married couples.
One couple is clearly (B, C).
The second couple could be:
• (D, E) ⇒ E male, or
• (A, E) ⇒ A male, or
• (A, someone) depending on relations not specified.
Since the gender of A and E is not fixed by the data, the total number of male members can vary.
Therefore, the exact number of male members cannot be uniquely determined.
Correct conclusion: Cannot be determined
• One married couple is clearly B–C (given: C is the wife of B).
• The problem states there are two married couples.
• D is a grandmother and mother → D is female.
• F is the granddaughter of E → E must be older than F and can be male.
There is no condition contradicting D being married to E. Hence, D–E can be the second couple.
Answer: D and E
C is wife of B ⇒ B is male, C is female.
D is grandmother ⇒ D is female.
F is granddaughter ⇒ F is female.
Gender of A is not given.
So A cannot be surely brother/sister of F, and B having two daughters is also not sure.
