Question

A truck driver charges Rs.2000 for 10 km with a load of 800kg. What will he charge if truck covers a distance of 8km with a load of 600kg?
​

Answer 1

subtract everything from 200=

                                               =2000-200=1800

10-2=8

800-200=600

for 1 km the cost =2000/10=200

200*8=1600

for 1 kg 800/600=8/6=4/3

=4/3*200
