Correct answer: (A) 1125
Passed in at least one subject = 100% - 15% = 85%. Passed in both = (Passed in Hindi + Passed in English) - Passed in at least one = 65% + 48% - 85% = 28%. So 28% of total = 315 → Total = 315/0.28 = 1125.

सही उत्तर: (A) 1125
कम से कम एक विषय में उत्तीर्ण = 100% - 15% = 85%। दोनों में उत्तीर्ण = (हिंदी में उत्तीर्ण + अंग्रेजी में उत्तीर्ण) - कम से कम एक में उत्तीर्ण = 65% + 48% - 85% = 28%। अतः कुल का 28% = 315 → कुल = 315/0.28 = 1125।
