Correct answer: C. 55:27

Explanation

Take B = 200, C = 300 students. B passed = 55% of 200 = 110; males = 110 × 5/8 = 68.75. C failed = 30% of 300 = 90; females = 90 × 3/8 = 33.75. Ratio = 68.75 : 33.75 = 55:27.B = 200, C = 300 छात्र मान लीजिए। B में उत्तीर्ण = 200 का 55% = 110; पुरुष = 110 × 5/8 = 68.75। C में अनुत्तीर्ण = 300 का 30% = 90; महिलाएँ = 90 × 3/8 = 33.75। अनुपात = 68.75 : 33.75 = 55:27।
