Answer:
given, ratio of student to teacher ratio = 35:1
no. of students joining next year = 280
let no. of teachers needed next year = y
now by proportion
35:1::280:y
35y = 280 (product of means equals the product of the extremes)
y = 280/35
y = 8
therefore the no. of new teachers required for next year is 8
