पुढे दिलेले एका वर्गातील विद्यार्थ्यांच्या भाषा बोलण्याच्या अस्खलिततेचे वेन निर्देशन अभ्यासा. किती विद्यार्थी कोणत्याही फक्त तीन भाषा अस्खलितपणे बोलू शकतात ? (वर्णाक्षरे विभिन्न संख्या निर्देशित करतात)
पर्यायी उत्तरे :

The correct answer is Option B (K + I + H).

Key Points:
• The Venn diagram represents fluency in four languages: English (Circle), Hindi (Triangle), Marathi (Rectangle), and a South Indian Language (Irregular Loop).
• We need to find the regions that belong to the intersection of EXACTLY THREE shapes (three languages only):
• Region H: Lies at the intersection of Circle (English), Triangle (Hindi), and Rectangle (Marathi), but outside the South Indian language loop.
• Region I: Lies at the intersection of Triangle (Hindi), Rectangle (Marathi), and the South Indian language loop.
• Region K: Lies at the intersection of Circle (English), Rectangle (Marathi), and the South Indian language loop.
• Region M falls inside all four overlapping shapes (speaks all 4 languages).
• Thus, the students speaking ONLY any three languages are represented by K + I + H.
• Hence, option (2) is correct.
• Key Takeaway: Regions H, I, and K represent intersections of exactly three language boundaries, giving K + I + H.
