The sum of the number of boys and girls in a school is 150. If the no. of boys is x, the number of girls becomes x% of the total number of students. The number of boys is?
Answer & explanation
Correct answer: option 4
Boys + Girls = Total no. of students
x + x% × 150 = 150
x + \(\frac{x × 150 }{100}\) = 150
100x + 150x = 15000
250x = 15000
x = \(\frac{15000}{250}\) = 60
