Answer:
Step-by-step explanation:
let 15 be 15x
let 1 be 1x
boys before the principal's effort = 15x
girls before the principal's effort = 1x
boys after the principal's effort = 7x
girls after the principal's effort = 5x
Now, the present
strength of boys is 8 more than the number of girls = (7x)(8) x 5x
= 56x x 5x
=280x
therfore the total
strength of students in school = 7x + 280x
find the value of x
hope this helps, this is all i know
