Question
In a certain school, 60% of the students are girls, and
the rest are boys. If the number of boys in the school is 480, how many students are there in total?Solution
Let the total number of students be x. Since 60% are girls, 40% are boys. According to the question, the number of boys is 480, so 40% of the total students is 480. Thus, 40% of x = 480 (40/100) × x = 480 x = 480 × (100/40) x = 1200 Therefore, the total number of students is 1200. Correct answer: b. 1200
