Question

In a school, the boys and girls are in the ratio 9 : 5. If there are 425 girls, what is the total number of students in the school?

KnowledgeBoat · Accepted Answer

Given, Boys : Girls = 9 : 5 Let number of Boys = 9x and Girls = 5x. Total number of girls in school = 425 So, ⇒ 5x = 425 ⇒ x = ⇒ x = 85. Therefore, Number of Boys in school = 9x = 9(85) = 765. Total number of students in school = 765 + 425 = 1190. Hence, the total number of students in the school = 1190.
