Understanding the Subject Skills

The problem requires us to identify a single individual who is proficient in four specific subjects: History, Physics, Computer Science, and Mathematics. We need to carefully examine the provided statements about the skills of Madhu, Shobha, Anjali, Poonam, and Nisha.

The given information can be broken down as follows:

• Madhu and Shobha are good in Dramatics and Computer Science.
• Anjali and Madhu are good in Computer Science and Physics.
• Anjali, Poonam, and Nisha are good in Physics and History.
• Nisha and Anjali are good in Physics and Mathematics.
• Poonam and Shobha are good in History and Dramatics.

Compiling Proficiency Data

To effectively determine who meets all the criteria, it's helpful to consolidate the information for each person across all mentioned subjects. A table can summarize this data clearly.

Identifying the Candidate with All Skills

The core task is to find the person proficient in History, Physics, Computer Science, and Mathematics. Let's evaluate each individual based on the compiled list:

• Madhu: Madhu is good in Computer Science and Physics. However, there is no information indicating Madhu is good in History or Mathematics.
• Shobha: Shobha is good in Computer Science and History. Shobha is not mentioned as being proficient in Physics or Mathematics.
• Anjali: Anjali is mentioned as being good in Computer Science, Physics, History, and Mathematics. This covers all the required subjects.
• Poonam: Poonam is good in Physics and History. Information does not suggest proficiency in Computer Science or Mathematics.
• Nisha: Nisha is good in Physics, History, and Mathematics. However, Nisha is not mentioned as being proficient in Computer Science.

By cross-referencing the skills required (History, Physics, Computer Science, and Mathematics) with the proficiency data, it is clear that Anjali is the only person who meets all the specified criteria.
