Question

The ratio of the number of girls to the number of boys in a school is 2 : 5. If the number of boys is 225 ; find:
(i) the number of girls in the school.
(ii) the number of students in the school.

Answer 1

Answer:

90,315

Step-by-step explanation:

let the students be x

then no of boys = 5x

no of girls = 2x

also, according to question,

5x = 225

= x= 225/5 = 45

1) so no of girls = 2x = 2× 45 = 90

2) total students = no of boys + no of girls = 225+90 = 315
