These questions are based on the following information.
Each of the four boys Chandu, Vanda, Bittu and Nattu is studying in a different school among – SKC, DAV, CCS and BBS. Each of their mothers is teaching in a different school among those given above, not necessarily in the same order. We also know that:
The mother of the boy who studies in SKC, teaches in CCS.
Bittu's mother teaches neither in CCS nor in BBS.
Nattu studies in CCS and Vanda's mother teaches in SKC.
None of the boys studies in the same school where his mother teaches.
Who studies in DAV?
Show answer & explanation
Correct answer: A
Explanation
Based on the given information, we can deduce the schools for the boys and their mothers:
• Nattu's school: Nattu studies in CCS (given).
• Vanda's mother's school: Vanda's mother teaches in SKC (given).
• Boy studying in SKC: The mother of the boy who studies in SKC teaches in CCS.
• Nattu studies in CCS, so he does not study in SKC.
• If Vanda studied in SKC, his mother would teach in CCS, but she teaches in SKC. So, Vanda does not study in SKC.
• If Bittu studied in SKC, his mother would teach in CCS, which is explicitly contradicted by the clues. So, Bittu does not study in SKC.
• Therefore, Chandu studies in SKC, and Chandu's mother teaches in CCS.
• Bittu's mother's school: Bittu's mother does not teach in CCS or BBS, and SKC is already taken by Vanda's mother. Therefore, Bittu's mother teaches in DAV, which leaves Nattu's mother teaching in BBS.
• Boys in DAV and BBS: The remaining boys are Vanda and Bittu, and the remaining schools are DAV and BBS.
Since no boy studies where his mother teaches, Bittu cannot study in DAV (as his mother teaches in DAV). Thus, Bittu studies in BBS and Vanda studies in DAV.
Therefore, Vanda studies in DAV.
