Question

The Chatterjee family has 8 members: A, B, C, D, E, F, G, H. There are 3 generations in the family. They go to 4 different countries: France, Canada, UK, and USA. They make 4 groups of 2 members each, and each group goes to one country. The family consists of 3 married couples, and each couple forms a group. The following conditions are given:
1. The family consists of 3 married couples and each couple forms a group.
2. The oldest member of the family goes to Canada.
3. H, a female, is married to E, who does not go to UK.
4. B and Dform a group and agreed to go to USA.
5. E’s mother-in-law is the mother of C, who is the father of B and brother of H.
6. A is the grandfather of one of the male members, who goes to USA.
7. D is unmarried and the niece of C.
8. F is the oldest member of the family.
Whois the mother-in-law of E?

• A. G
• B. F
• C. A
• D. Cannot be determined

Hint:

In logical reasoning questions involving family relationships and grouping logic, start by identifying all generations, genders, and pairings. Assign known values first, then deduce missing ones based on constraints.

Answer 1

The Correct Option is B

Step 1: Use condition 8: F is the oldest member.
From condition 2: $$ \Rightarrow \text{F goes to Canada} $$ Step 2: From condition 7: D is unmarried and niece of C. $$ \Rightarrow \text{C is male and D's uncle.} $$ Step 3: From condition 5: E’s mother-in-law is the mother of C, who is the father of B and brother of H.
So:
C is male
C is father of B
C is brother of H
E is married to H (from condition 3)
$$ \Rightarrow \text{H is E’s wife} \Rightarrow \text{E’s mother-in-law = mother of H and C} $$ Let’s denote this unknown person as X. Step 4: From condition 6: A is the grandfather of one of the male members who goes to USA.
From condition 4:
B and D go to USA
B is male → A is B’s grandfather
Since C is B’s father → A is also C’s father $$ \Rightarrow \text{A is also grandfather of D (if D is C's niece)} $$ Step 5: Determine identity of X (mother of C and H, i.e., E’s mother-in-law)
We know:
A is father of C and H
So X is their mother
Remaining females: F (oldest), H (wife of E), D (youngest)
From condition 8:
F is oldest
F goes to Canada
No direct info on gender of G or E
But from condition 5:
E’s mother-in-law = mother of C
And we’re told F is the oldest member — which fits better with being the grandmother (mother of C and H) $$ \Rightarrow \text{F is likely the mother of C and H} \Rightarrow \text{F is E’s mother-in-law} $$ Conclusion: $$ \boxed{\text{(B) F}} $$
