Answer:
28 passengers
Step-by-step explanation:
let no. of passengers with ₹5ticket be x
with ₹7.50 be y
we know total no. of passengers is 40
I.e. x+y=40
y=40-x eq1
total fare =₹230
5x+7.5y=230
from eq1
5x+7.5(40-x)=230
5x-7.5x+300 =230
-2.5x=230-300
x=-70/-2.5
x=700/25
x=28
therefore no. of passengers with ₹5 ticket is 28
