Show answer & explanation
Correct answer: D. 21:11
Explanation
Let passed students in each college = P. B: pass 55%, so failed = P × 45/55 = 9P/11. C: pass 70%, so failed = P × 30/70 = 3P/7. Ratio = 9/11 : 3/7 = 63 : 33 = 21:11.मान लीजिए प्रत्येक कॉलेज में उत्तीर्ण छात्र = P। B: उत्तीर्ण 55%, अतः अनुत्तीर्ण = P × 45/55 = 9P/11। C: उत्तीर्ण 70%, अतः अनुत्तीर्ण = P × 30/70 = 3P/7। अनुपात = 9/11 : 3/7 = 63 : 33 = 21:11।More Data Interpretation questions
