(Only quantity is to be considered) निम्नलिखित प्रत्येक प्रश्न में दिए गए कथन को पढ़ें और उसके आधार पर मात्रा I और मात्रा II की तुलना करें। (केवल मात्रा पर विचार किया जाना है|) The ratio of boys to girls in a school is 4: 5. If 45 students from the same school left in the same ratio and 40 new girls joined the school, then the ratio of boys to girls becomes 4:9. एक विद्यालय में लड़कों का लड़कियों से अनुपात 4: 5 है। यदि उसी स्कूल के 45 छात्रों उसी अनुपात में विद्यालय छोड़ देते है और 40 नई लड़कियां विद्यालय में शामिल हो जाती हैं, तो लड़कों का लड़कियों से अनुपात 4: 9 हो जाता है। Quantity I: What percentage of total students will be boys if 50% of the total number of boys leave the school?
