Answer 1

Answer:

90 Rs/students

Step-by-step explanation:

12.5% means 1/8

so let consider total cost ( in Rs) = 8x

want to earn ( in Rs) = 9x

so Rate = 9x/24

but at last only 21 student come so he earn from these is equal to = 21 × 9x/24 in Rs

above earning ,he lost 30 rs from intial coast

21 × 9x/24 = 8x-30

on solving we get, x = 240

so rate = 9 × 240 / 24 = 90
