Fare, number of luggage and distance are all directly related.
f = k(nd)

Solve for "k" using "the fare of 12 quintal luggage for a distance of 18km is 20 rupees"
20 = k(12*18)
k = 0.09259
---
Equation:
f = 0.09259nd
-----------
Solve:"how much fare be aluggage of 8 quintal for a distance of 20km? 
f = 0.09259*8*20
f = 14.82 rupee
