गणना:

उपस्थित विद्यार्थियों की कुल संख्या = 1800 विद्यार्थी 

⇒ 360° = 1800

⇒ 1° = 1800/360 = 5 विद्यार्थी 

अनुभाग A में उपस्थित विद्यार्थी = 42° = 42 × 5 = 210 विद्यार्थी 

अनुभाग B के उपस्थित विद्यार्थी = 50° = 50 × 5 = 250 विद्यार्थी 

अभीष्ट अंतर = (250 - 210) = 40 विद्यार्थी 

∴ सही उत्तर 40 विद्यार्थी हैं।
