Show answer & explanation
Correct answer: A. 149:51
Explanation
Take 100 students in D. Passed = 45: males 45 × 4/5 = 36, females 9. Failed = 55: males 55 × 7/10 = 38.5, females 16.5. Males = 74.5, females = 25.5, so ratio = 745 : 255 = 149:51.D में 100 छात्र मान लीजिए। उत्तीर्ण = 45: पुरुष 45 × 4/5 = 36, महिलाएँ 9। अनुत्तीर्ण = 55: पुरुष 55 × 7/10 = 38.5, महिलाएँ 16.5। कुल पुरुष = 74.5, महिलाएँ = 25.5, अतः अनुपात = 745 : 255 = 149:51।More Data Interpretation questions
