Question
The total strength of school A is 20% more than that of
school B. In school A and B, out of total number of students, 30% and 40% respectively are girls. The number of boys in school A is how much percent more/less than that in school B?Solution
Let the total number of students in school B be ‘x’. Therefore, total number of students in school A = 1.2x Number of boys in school A = 0.70 × 1.2x = 0.84x Number of boys in school B = 0.6x Required % = [(0.84x – 0.6x)/0.6x] × 100 = 40%
