Re: 10 second questionsHi bobbym, #4313. The sum of the number of boys and girls in a school is 150. If the number of boys is x, then the number of girls becomes x% of the total number of students. What is the number of boys? #4314. In an examination of n questions, a student replied 15 out of the first 20 questions correctly. Of the remaining questions, he answered onethird correctly. All the questions have the same credit. If the student gets 50% marks, what is the value of n? Character is who you are when no one is looking. #4177 20120916 20:32:04
